Document Summary

Projectile motion: change of position of an object after it is propelled into the air (human does not count) The relationship between position, velocity, and acceleration, describes the trajectory that a projected object will travel. Two forces act to change the trajectory of a projectile: gravity, air resistance (minor in most cases) Want to even out vertical and horizontal axis"s so it can travel farthest. 1: maximum vertical distance with some horizontal, maximum horizontal distance (vhorz) Greater v of projectile = greater fdrag. On descent, acceleration influenced by gravity and air friction (air friction its there but is not a huge component) Gravity is only thing causing acceleration after highest point: height of c of g at takeoff point, vvert of c of g at takeoff (greater = higher, location of body segments at apex jumping strategies & techniques. Tumbling- jumps reaching great heights while moving rom corner to corner. High jump- vary body from takeoff to pit.
