  1. Today we went over Displacement, displacement is like distance but it can never be greater than distance no matter what. Displacement can be used to find measurement or the distance between things.
    We also learned a little more about velocity. Velocity has both positive and negative charges. When its either going down or the opposite way its always negative velocity. You always divide by the number of velocity's so if there's 3 of them you divide by 3.
    Acceleration is the change in velocity. The difference between acceleration and velocity is acceleration is always squared.
    We went over equations in class on how to find the average of acceleration in time period and what is the initial velocity in the time interval. To find units, units are always next to numbers.
