Document Summary
How much displacement are you covering per unit of time. Acceleration is mathematically liked with velocity and displacement. If not changing velocity, then don"t have an acceleration at all. Change in velocity: velocity at point 1 vs point 2. Can rearrange equation to determine an unknowns average vs. instantaneous: Velocity starts at zero and in static position. Have negative velocity= approaching ground with hip. Start going back he other way and go back to zero- when they stop approaching the ground. Now getting positive values= hip getting further away from the ground. The instant after you reach maximal velocity point you left the ground, then will travel upwards because of positive velocity until you reach high point and then you"ll start to go down very fast but negative velocity. Have maximum positive velocity in vertical direction of 2. 5 m/sec. Can describe the movement of this person in a lot of detail. Velocity and displacement are examples of vector quantities.
