Ch 10- linear kinematics

Distance & Displacement describes what? extend of a body's motion
Distance Length of the path that a body follows when moving from one location to the next (Scalar)
Displacement length of (imaginary) line joining starting position and finishing position and noting direction (vector)
speed distance / change in time
velocity (displacement/chance in time) & direction
Instantaneous speed average speed over a very small distance or unit of time so that the speed does not have time to change
How do you max vertical jump? -lower CG in relation to the body -apply as much force to the ground during jumping phase
Acceleration rate of change in velocity
in a race, where is the greatest force? at the beginning b/c you have less velocity
Acceleration equation (V final - V initial) / delta T = Delta V / Delta T
In a race, where is the greatest force? At the beginning because you have less velocity. (FORCE ^ - VELOCITY v)
