1. Aristotle divided motion into two main classes:Natural Motion and Violent Motion.
2. Aristotle asserted that natural motion proceeds from the "nature" of an object, dependent on what combination of the four elements (earth, water, air, and fire) the object contains.
3. Violent motion results from pushing or pulling forces. Violent motion was imposed motion.
4.Galileo was concerned with how things move rather than why they move. He showed that experiment rather than logic is the best test of knowledge.
5. Everything moves-even things that appear to be at rest.
6.Galileo found that a ball rolling down an inclined plane picks up the same amount of speed in successive seconds.
7 Inertia is the slugishness or apparent resistance of an object to change its state of motion. Mass is the measure of inertia.
8.In Aristotle's view evert object in the universe has a proper place, determined by this nature; any object not in his proper place will strive to get there.
9.Nicolaus Copernicus formulated his story of the moving Earth.
10.Galileo is said to have dropped Various objects from the leaning tower of Pisa and compared their falls.
1. Aristotle was the first to study motion. He asserted that natural motion proceeds from the nature of an objective that depends on the four elements - earth, water, air, and fire.
2. Aristotle taught that all motions are due to the nature of the moving object or due to the pull or push. Force moves an object.
3. Galileo dropped objects of various weight from the top of the Leaning Tower of Pisa to test Aristotle's falling-body hypothesis. He disproved Aristotle's hypothesis.
4. Newton got his first law of inertia from Galileo's idea. The first law of motion states that every object continues at its state of rest and only changes if force is applied to it.
5. When Copernicus introduced the idea that the Earth is always moving, inertia was misunderstood by the people. Physics is everywhere.
6. Things that appear at rest are moving. They move relative to the Sun and stars.
7. Before the time of Galileo, people described things as moving slow or fast. Motion is relative.
8. Rapid deceleratoin is sensed by the driver and not the car. The driver leaps forward with the sudden brake.
9. The motion of heavier objects such as stones or baseballs at low speeds is not affected by the air. A feather and a coin fall at equal accelerations in a vacuum.
10. How far an object falls is altogether different from how fast it falls.
1) Aristotle divided motion into two main classes: natural motion and violent motion.
2) Aristotle asserted that natural motion proceeds from the "nature" of an object, dependent on what combination of the four elements (earth, water, air, and fire) the object contains.
3) Natural motion could be either straight up or straight down, as in the case of all things on Earth, or it could be circular, as in the case of celestial objects.
4) By the time Newton was 23, he developed his famous laws of motion, which completed the overthrow of the Aristotelian ideas that had dominated the thinking of the best min
1. Galileo was the first to provide conclusive refutation through observation and experiment. He dropped objects of various weights from the top of the Leaning Tower of Pisa and compared their falls. 2.Galileo's observation of motion along smoother surfaces: when there was less friction, the motion of objects persisted or a longer time; the less the friction, the more motion approached constant speed. 3.Every object continues in its state of rest, of of uniform motion in a straight line, unless its compelled to change that state by forces impressed upon it. 4.If an object is moving, it continues to move without turning or changing its speed. this is evident in space probes that continually move in outer space. 5.if you put a book on a table, the table pushes up on the book with as much force as the downward force of gravity on the book. If it was a spring, the spring would be pushing up on your hand with as much force as you exert to push down on it. 6.if you get a traffic ticket for speeding, its because your instantaneous speed or average speed... 7. we say that a body undergoes acceleration when there is a change in its state of motion. 8. when someone hammers a nail in wood on top of 3 books on your head, it wont hurt you. 9. string has the same magnitude as a bag. so the net force is zero. 10. everything not undergoing changes in motion is in mechanical equibrilium. 11.average speed = total distance covered / time interval 12. total distance covered= average speed x time 13. acceleration (car) = change of velocity/time interval 14. the greater slope of the acceleration of the ball is due to the greater incline of the ramp. 15. velocity acquired = acceleration x time 16. free fall- the effect of gravity alone. 17. distance traveled = 1/2 (acceleration x time x time) 18. d=1/2 gt squared 19. a feather and a coin fall at equal accelerations in a vaccum. 20. a speedometer gives readings in both miles per hour and kilometers per hour.
1. Aristotle's idea of violent motion, he claimed, resulted from pushing or pulling forces. Violent motion imposed motion.
2. Aristotle's views became a very formidable part of Church doctrine so to contradict Aristotle's views was to contradict the Church.
3. Galileo attracted a large crowd to witness the dropping of two objects of different weight from the top of a tower. Supposedly, although the two fell at the same time, the crowd didn't believe Galileo and held tight to Aristotle's beliefs.
4. Aristotle was an astute observer of nature, and he dealt with problems around him than with abstract cases that didn't occur in the environment.
5. Isaac Newton adopted his first law of motion from Galileo's idea. Newton was born only months after Galileo.
6. Isaac Newton was born prematurely and barely survived. He was born on Christmas Day.
7. Everything not undergoing changes in motion is in mechanical equilibrium.
8. We accelerate whenever we move in a curved path, even if we're moving at constant speed because our direction is changing so our velocity is changing.
9. During each second of fall, the object gains a speed of 10 meters per second.
10. The formula for distance traveled: 1/2 (acceleration X time X time )
The first thing i liked about chapter 2 was the fact that,aristotle's statements were a beginning in scientific thought.
The second thing i liked about chapter 2 was the fact that Renaissance times was the nation that the normal state of objects is one of rest.
The third thing i liked about chapter 2 was that the concept of violent motions had its difficulties for, for the pushes and pulls responsible for it were not always evident.
The fourth thing i liked about chapter 2 was that about Copernicus and the moving earth, most of us know about the reaction of the medieval to the idea of the earth travels around the sun.
The fifth thing i liked about chapter 2 was that about Copernicus and the moving earth,that for better or worse ,this new idea was to over turn their concept of the cosmos,although eventually the church embraced it.
The sixth thing i liked about chapter 2 was that about Galilo,the foremost scientist of the early seventeenth century,he gave credence to the Copernican view of the moving earth.
The seventh thing i liked about chapter 2 was that Galileo easily demolished Aristotole's falling- body hypothesis.
The eight thing i liked about chapter 2 is that Galileo is said to have dropped objects of various weights from the top of the leaning tower of pisa.
the ninth thing i liked about chapter 2 was that Aristotle dealt with problems around him rather than with abstract cases that did not occur in his environment.
The tenth and final thing that i learned about chapter two was that all of these phylosaphers were all thinkers and they all had ideas in the way of life.
1. Aristotle asserted that natural motion proceeds from the "nature" of an object, dependent on what combination of the four elements (earth, water, air, and fire) the object contains. In his view, every object in the universe has a proper place, determined by this "nature"; any object not in its proper place will "strive" to get there.
2. Copernicus reasoned that the simplest way to account for the observed motions of the Sun, Moon and planets through the sky was to assume that Earth (and other planets) circle around the sun.
3. Galileo denied when he stated that, if there is no interference with a moving object, it will keep moving in a straight line forever; no push, pull, or force of any kind is necessary.
4. It was Galileo, the foremost scientist of the early seventeenth century, who gave credence to the Copernican view of a moving Earth. He accomplished this by discrediting the Aristotelian ideas about motion.
5. Aristotle believed vacuum to be impossible and therefore did not give serious consideration to motion in the absence of an interacting medium.
6. Aristotle`s idea that a moving object must be propelled by a steady force was completely turned around by Galileo, who stated that, in the absence of a force, a moving object will continue moving.
7. When Newton was 42 he began to write what is generally acknowledge as the greatest scientific book ever written, the Principia Mathematica Philosophiae Naturalis.
8. Newton showed that the universe operated according to natural laws that were neither capricious nor malevolent.
9. When Copernicus announced the idea of a moving Earth in the sixteenth century, the concept of inertia was not understood.
10. If Copernicus were correct, Earth would have to travel at a speed of 107,000 kilometers per second.
1. Natural motion is when the object proceeds from the nature of an object.
2. Violent motion is the result of imposed forces (pushing and pulling).
3. The earth moving was based off the idea that the other planets were moving around the sun.
4. Objects of different mass, fall at the same rate.
5. If a object was moving, and there was no forces to stop it, it would go on forever.
6. A downward slope increases speed, a upward slope decreases speed, and no slope, has no applying forces on it.
7. Every object continues in its state of rest, or of uniform motion in straight line, unless it is compelled to change that state by forces impressed upon it.
8. If an object is moving, it continues to move without turning or changing its speed.
5) Aristotle's idea that a moving object must be propelled by a steady force was completely turned around by Galileo, who stated that, in the absence of a force, a moving object will continue moving. 6) The tendency of things to resist changes in motion was what Galileo called inertia. 7) Newton refined Galileo's idea and made it his first law, appropriately called the law of inertia. 8) Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it. 9) In the absence of net forces, a moving object tends to move along a straight-line path indefinitely. 10) A force, in the simplest sense, is a push or a pull. 11) Galileo defined speed as the distance covered per unit of time. 12) When we know both the speed and the direction of an object, we know its velocity. 13) A quantity such as velocity that specifies direction as well as magnitude is called a vector quantity. 14) Constant speed means steady speed. 15) If either the speed or the direction changes (or if both change), then the velocity changes. 16)Acceleration is how quickly velocity changes. 17) When a falling object is free of all restraints-no friction, with the air or otherwise-and falls under the influence of gravity alone, the object is in a state of free fall. 18) Galileo found that the distance a uniformly accelerating object travels is proportional to the square of the time. 19) It took people nearly 2000 years from the time of Aristotle to reach a clear understanding of motion. 20) Acceleration is not velocity, nor is it even a change in velocity.
Chapter 2 1. Aristotle divided motion into 2 main classes: natural motion and violent motion. 2. Aristotle also asserted that natural motion proceeds from the nature of an object, depending on the combination of the four elements (earth, water, wind, and fire). 3. Natural motion could be either straight up or down. 4. Violent motion results from pushing or pulling forces. 5. Law of Inertia- every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state be forces impressed upon it. 6. Force in the simplest sense, is push or pull. 7. The equilibrium rule provides a reasoned way to view all things at rest. 8. Net Force- the vector sum of forces that act on an object. 9. When the net force on something is zero, we say that something is in Mechanical Equilibrium. 10. Equilibrium Rule- for any object or system of objects in equilibrium, the sum of the forces acting equals zero.
Chapter 3 1. Everything moves even if it appears at rest. 2. Galileo defined speed as the distance covered per unit of time. 3. Any combination of distance and time units is legitimate for measuring speed. 4. The speed at any instant is the instantaneous speed. 5. If you know both speed and the direction of an object then you know the velocity. 6. A quantity such as velocity that specifies direction as well as magnitude is called a Vector Quantity. 7. Velocity is a vector quantity. 8. Acceleration- the rate at which velocity changes with time. 9. The change in velocity may be in magnitude, or direction, or both. 10. Free Fall- when the object is free of all restraints and falls under the influence of gravity.
1) Aristotle divided motion into two main classes: natural motion and violent motion.
2) Copernicus observed motions of the Sun, Moon, and planets through the sky and assumed that Earth ( and to other planets) circle around the sun. He kept his work to himself because he feared being prosecuted and he had doubts about it himself.
3) Galileo was the first to provide conclusive refutation through observation and experiment. He easily proved Aristotle's falling-body hypothesis. He dropped two objects of various weights from the top of the Leaning Tower of Pisa and had to have compared their falls.
4) Newton refined Galileo's idea and made it his first law, appropriately called the law of inertia. Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it. The key word in this law is continues: and object continues to do whatever it happens to be doing unless a force is exerted upon it.
5) Changes in motion are produced by a force or combination of forces. A force, in the simplest sense, is a push or a pull. Its source may be gravitational, electrical, magnetic, or simply muscular effort.
6) If a moving object is moving, it continues to move without turning or changing its speed.
Chapter 2 1. Aristotle believed that an object twice as heavy as another would fall twice as fast. 2. Copernicus believed that the earth and the other plants rotated around the sun, he kept this theory to himself for many years. One of the reasons he did that was because he doubted himself. The second reason he did that was because he feared being persecuted. He finally told his beliefs on the last days of his life. 3. Galileo proved that the weight of an object does not effect how fast they will fall 4. Galileo was arrested for going against the church 5. Newton's first law of motion: Every object continues in its state of rest, or of uniform motion in a straight line, unless compelled to change that state by forces impressed upon it. 6. Galileo noted that balls rolling on downward sloping planes picked up speed 7. He also noted that balls rolling on an upward sloping plane lost speed. 8. He reasoned that balls rolling on a horizontal plane would neither increase or decrease in speed.
1. Natural motion could be either straight up or straight down, as in the case of all things on Earth, or it could be circular, as in the case of celestial objects. 2. Violent motion is a person pushing a cart or lifting a heavy weight imposed motion, as did someone hurling a stone or winning a tug of war. 3. To sum up, Aristotle taught that all motions are due to the nature of the moving object, or due to a sustained push or pull. 4. Nicolaus Copernicus was the Polish astronomer who formulated his theory of the moving Earth. 5. For years Copernicus worked without making his thoughts public for two reasons. The first reason was that he feared persecution. The second reason was that he led grave doubts about it himself. 6. Galileo found that a stone twice as heavy as another did not fall twice as fast. Galileo allegedly attracted a large crowd to witness the dropping of two objects of different weight from the top of the tower. 7. Newton showed that the universe operated according to natural laws that were neither capricious nor malevolent . It was a knowledge that provided hope and inspiration to scientist, writers, artists, philosophers, and people of all walks of life. 8. The ideas of Isaac Newton truly changed the world and elevated the human condition.
the first thing i saw that interests me was the story of galileo and the leaning tower he used weights to disprove aristotles thought that if an object weighs more it falls with greater force he actually went to the top of the leaning tower of pisa and dropped two weights of complete different weights
the second thing that i saw that i liked in chapter 2 was the equilibrium rule i liked learning how tension works on springs and scales it is very interesting it relates to newtons first law of mechanical equilibream
the other thing i saw that i likedwas how gravitational force and support force work its interesting that when you stand on a scale tecnicly it measurs the force pressed on it not the weight
another thing i saw was the effect that newtons first law of motion has on different objects such as when you are holding a hammer and you bring it down vertically the hammerhead tightens this is because of the fact that the hammer head is still traveling after the hammer has stopped this sending it downward and tightening it
another thing isaw
another thing i saw that i thought was cool the thing that i saw was about the moving earth and about copernicus's thought or theory that the earth was always moving and that he figured out that the planet moves at 30 kilometers per second and the ague ment was that if we were rotating that far than if a bird could not drop straight down from a tree the earth would have moved the worm out of the birds way then we would be at rest however we do travel this fast and birds do catch worms its newtons law that things in motion remain in motion
another thing about newtons first law was that if you are riding in an airplane going really fast and flip a coin the coin flips exacty the same as if you were on land
one other thing that i saw that was interesting was the fact that gallileo was once arrested for publishing his findings and put in house arrest however he was still able to smugge his findings out of italy and to holland to be published
another thing that i learned was that gallileo had once damaged his eyes by looking at the sun through a telliscope this later led to him becoming blind in his seventys
another thing i learned was that after plato died aristotle became the tutor of the young alexander the gret who would later become one of the greatest rulers and militant men of all time and later aristotle started his own acadamy which was cool
I learned Aristotle stated that heavier objects would strive harder, he said the heavier the object, the faster it should fall.
Aristotle divided motion into two main classes, Natural motion and Violet motion, Natural motion could be either straight up or straight down. Violent motion, is resulted from either pushing or pulling forces.
I also learned that Nicolas Copernicus formulated his theory of the moving earth, that the earth its self moved without us moving. He also assume that earth and other planets circled around the sun.
The telescope was first built by Galileo Galilei, he found so many interesting things, like mountains on the moon and the moons of jupiter. He also invented the printing press.
The world knew after Galileo was looking threw his telescope at the sun to much that later that led to blindness.
When there is less friction to something the object persisted for a longer time, the less the friction, the more the motion approached constant speed.
Galileo reasoned that in the absence of friction or other opposing forces, a horizontally moving object would continue moving indefinitely.
Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change the state by forces impressed upon it
Changes in motion are produced by a force or a combination of forces. Force means push or pull.
1) Aristotle divided motion in to main classes, natural motion and violet motion, there not consider each, not as study motion.
2) Natural motion could be either straight up or straight down , as in the case of all the things on Earth, or it could be circular, as in the case of celestial objects.
3) Aristotle asserted that natural motion proceeds from the "nature", dependent on what combination of the four element(earth, water, air,and fire).
4) Aristotle taught that all motions are due to the nature of the moving object, or due to a sustained push or pull.
5) Since it was evident to most thinkers until the sixteenth century that earth must be in its proper place.
6) It was intellectual climate that the polish astronomer Nicolaus Copernicus (1474- 1543) formulated his theory of the moving earth.
7) Galileo was the best scientist of the early seventeenth century, who gave credence to the Copernican view of a moving Earth.
8) Galileo was the first to provide conclusive refutation through observation and experiment.
9) Galileo tested this hypothesis by experimenting with the motion of various objects on plane surfaces.
10) The tendency of things to resist changes in motion was what Galileo called inrtia.

Galileo noted that balls rolling on downward sloping planes picked up speed 7. He also noted that balls rolling on an upward sloping plane lost speed. 8. He reasoned that balls rolling on a horizontal plane would neither increase or decrease in speed. 9. Aristotles idea was completly turned around by by Galileo who stated that in the absenceof a force a moving object will continue moving. 10. Object requires push or pull to keep it moving 11. Circular motion has no beginning or no end 12. Natural motion could be straight up or down 13. If an object is moving it continues to move with out turnig or changing its speed. 14. Changes in motion are produced by a force or combination. 15. in aristotles view every object in the universe has a proper place detirmined by "nature" 16. An object continues to do whatever it is doing unless a force is exerted upon it. 17. Galileo is said to have dropped objects of various weights from the top of the leaning Tower of Pisa 18. Everything moves even things that appear to be at rest. 19. When we know the speed and direction of an object then we know its velocity 20. Free fall is when the objects fall under the gravity alone.
Chapter 2 1.Aristotle asserted that natural's motion procads form the nature of an object,dependent on what combination of the four elements (earth,water,air and fire). 2.Natural motion could be either straight up or straight down, as in the of all things one earth; or it could be circular, as the case of celestical objects. 3.Aristotle believed that diffrent rules apply in the hearind, and he asserted that celestial bodies are perfect spres made of a pertial object with any detectable variation on its face was the moon. 4.Violent Motion,Aristotles other class of motion, resulted from pushing or pilling forces. 5.Aristotle thought that all motions are due to the nature of the moving object or due to sustained push or pull. 6.Aristotle's statement about motion were a beginning in scientific thought,and although he did not consider them to be the final words on the subject, his followers for nearly 2000 years regarded his vies as beyond question. 7.Galileo, the foremost scientist of the early seventeenth centurywho gave arendence to the copernican view of a moving. 8.Galileo tested this hypothesis by experimenting with the motion of various objects on plane surfaces tilted at various angles. 9.In 1642, several months after Galileo died,Issac Newton was born, when he was 23, he developed his famous laws of motion which completed the overthrown of the Aristotelia ideas that had dominated the thinking of the best minds nearly two milennia. 10.Newton showed that the universe operated accordin to natual laws that were neither capricious nor malevolent a knowledge that provided hope and inspiration to scientists, writers,artists, philosophers and people of all walks of life and that ushered in the age of reasons. Chapter 3 1.Everything moves even things that appear to be at rest they move relative to the sun and stars. 2.Galileo developed the concept of acceleration in his experiments on inclined planes. 3.Galileo found that a ball rolling down an inclined plne picks up the same amount of speed in succesive seconds. 4.When a falling object is free of all restraints no friction, with the air or otherwise it falls under this influence of gravity alone, the object is in a state of free fall. 5.Much of the confusion that aries in analyzing the motion of falling objects comes about because it is easy to get "how fast" mixed up with "how far". 6.It is a common observation that many objects fall with unequel accelerations. For example a leaf feather or a sheet of paper may flutter to the ground slowly. 7.Galileo defined speed as the distance covered per unit of time. 8.Everythin not undergoing changes in motion is in mechanical equilibrium. 9.Acceleration is how quickly velocity canges. 10.During each second of fall the object gainsa speed of 10 meters per second.

CHAPTER.3 1. The ancient greek scientist were familiar with some of the ideas of physics that we study today. 2. everything moves even things that appear to be at rest. 3. moving at about 107,000 kilometers per hour relative to the sun,and you're moving even faster relative to the center of our galaxy. 4. Galileo is credited with being the first to measure speed by considering the distance covered and time it takes. 5. Galileo defined speed as the distance covered per unit of time. 6. Constant speed means steady speed. something with constant speed doesn't speed up ir slow down. 7. If either the speed or the direction changes ( or if both change), then the velocity changes. 8. When tje driver depresses the gas pedal( appropriately called accelerator), the passengers then experince acceleration( or pickup, as it is sometimes called) as they are pressed against their seats. 9.the term acceleratio applies to decreases as well as to increases in celocity. 10. Galileo found that a ball rolling down an inclined plane picks up the same amountof speed in successive seconds.
Chapter 2 1)Aristotle divide motion into two main classes:natural motion and violent motion. 2)Copernicus came up with the theory of a moving Earth. 3)Galileo found that objects of various weights, when released at the same time falltogether and hit the ground at the same time. 4)Galileo focused more on how things move rather than why they move. 5)Newton made Galileo's be his first law which was called the law of inertia. 6)if two friends pull in the same direction with equal forces on an object, the forces cambie to produce a net force twice as great. If you both push with equal force in opposite directions the force is zero. 7)Mechanical equilibrium is the net force on something that is zero. 8)If putting more weight in one scale than the other both of the scales will add up to you weight. 9)When flipping a coin in a high-speed airplane,it behaves as if the airplane were at rest. 10)Natural motion comes from the nature of an object.

ReplyDelete1. Aristotle was the first to study motion. He asserted that natural motion proceeds from the nature of an objective that depends on the four elements - earth, water, air, and fire.
2. Aristotle taught that all motions are due to the nature of the moving object or due to the pull or push. Force moves an object.
3. Galileo dropped objects of various weight from the top of the Leaning Tower of Pisa to test Aristotle's falling-body hypothesis. He disproved Aristotle's hypothesis.
4. Newton got his first law of inertia from Galileo's idea. The first law of motion states that every object continues at its state of rest and only changes if force is applied to it.
5. When Copernicus introduced the idea that the Earth is always moving, inertia was misunderstood by the people. Physics is everywhere.
6. Things that appear at rest are moving. They move relative to the Sun and stars.
7. Before the time of Galileo, people described things as moving slow or fast. Motion is relative.
8. Rapid deceleratoin is sensed by the driver and not the car. The driver leaps forward with the sudden brake.
9. The motion of heavier objects such as stones or baseballs at low speeds is not affected by the air. A feather and a coin fall at equal accelerations in a vacuum.
10. How far an object falls is altogether different from how fast it falls.

In his view, every object in the universe has a proper place, determined by this "nature"; any object not in its proper place will "strive" to get there.
2. Copernicus reasoned that the simplest way to account for the observed motions of the Sun, Moon and planets through the sky was to assume that Earth (and other planets) circle around the sun.
3. Galileo denied when he stated that, if there is no interference with a moving object, it will keep moving in a straight line forever; no push, pull, or force of any kind is necessary.
4. It was Galileo, the foremost scientist of the early seventeenth century, who gave credence to the Copernican view of a moving Earth. He accomplished this by discrediting the Aristotelian ideas about motion.
5. Aristotle believed vacuum to be impossible and therefore did not give serious consideration to motion in the absence of an interacting medium.
6. Aristotle`s idea that a moving object must be propelled by a steady force was completely turned around by Galileo, who stated that, in the absence of a force, a moving object will continue moving.

8. The ideas of Isaac Newton truly changed the world and elevated the human condition.
the first thing i saw that interests me was the story of galileo and the leaning tower he used weights to disprove aristotles thought that if an object weighs more it falls with greater force he actually went to the top of the leaning tower of pisa and dropped two weights of complete different weights
ReplyDeletethe second thing that i saw that i liked in chapter 2 was the equilibrium rule i liked learning how tension works on springs and scales it is very interesting it relates to newtons first law of mechanical equilibream
the other thing i saw that i likedwas how gravitational force and support force work its interesting that when you stand on a scale tecnicly it measurs the force pressed on it not the weight
another thing i saw was the effect that newtons first law of motion has on different objects such as when you are holding a hammer and you bring it down vertically the hammerhead tightens this is because of the fact that the hammer head is still traveling after the hammer has stopped this sending it downward and tightening it
another thing isaw
another thing i saw that i thought was cool
the thing that i saw was about the moving earth and about copernicus's thought or theory that the earth was always moving and that he figured out that the planet moves at 30 kilometers per second
and the ague ment was that if we were rotating that far than if a bird could not drop straight down from a tree the earth would have moved the worm out of the birds way then we would be at rest however we do travel this fast and birds do catch worms its newtons law that things in motion remain in motion
another thing about newtons first law was that if you are riding in an airplane going really fast and flip a coin the coin flips exacty the same as if you were on land
one other thing that i saw that was interesting was the fact that gallileo was once arrested for publishing his findings and put in house arrest however he was still able to smugge his findings out of italy and to holland to be published
another thing that i learned was that gallileo had once damaged his eyes by looking at the sun through a telliscope this later led to him becoming blind in his seventys
another thing i learned was that after plato died aristotle became the tutor of the young alexander the gret who would later become one of the greatest rulers and militant men of all time and later aristotle started his own acadamy which was cool

I learned Aristotle stated that heavier objects would strive harder, he said the heavier the object, the faster it should fall.
ReplyDeleteAristotle divided motion into two main classes, Natural motion and Violet motion, Natural motion could be either straight up or straight down. Violent motion, is resulted from either pushing or pulling forces.
I also learned that Nicolas Copernicus formulated his theory of the moving earth, that the earth its self moved without us moving. He also assume that earth and other planets circled around the sun.
The telescope was first built by Galileo Galilei, he found so many interesting things, like mountains on the moon and the moons of jupiter. He also invented the printing press.
The world knew after Galileo was looking threw his telescope at the sun to much that later that led to blindness.
When there is less friction to something the object persisted for a longer time, the less the friction, the more the motion approached constant speed.
Galileo reasoned that in the absence of friction or other opposing forces, a horizontally moving object would continue moving indefinitely.
Every object continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change the state by forces impressed upon it

6)if two friends pull in the same direction with equal forces on an object, the forces cambie to produce a net force twice as great. If you both push with equal force in opposite directions the force is zero.
7)Mechanical equilibrium is the net force on something that is zero.
8)If putting more weight in one scale than the other both of the scales will add up to you weight.
9)When flipping a coin in a high-speed airplane,it behaves as if the airplane were at rest.
10)Natural motion comes from the nature of an object.
Chapter 3
1)galileo was the first to defined speed as the distance covered per unit of time
2)When sitting in your chair your speed is zero relative to Earth but 30/km relative to the sun.
3)Knowing both your speed and direction of an object is said to be velocity.
4)How quickly velocity changes is acceleration.
5)There are three controls that change velocity in an automobile thtat is the gas pedal, the brakes and the steering wheel.
6)It took about 2000 years for people to reach a clear understanding of motion.
7)Everything moves, even things that appear to be at rest. They move relative to the sun and stars.
8)Constant velocity doesnt speed up or slow down.
9)Acceleration applies to decreases as well as to increases in velocity.
10)When things fall because of the force of gravity it is called free fall.
