Document Summary
The change in position of an object after its propelled in the air. What is the optimum angle of release for a shot putter to throw the maximum distance. Shot putter = 36 to 37 degrees. When throwing for max 45 degrees, because you even out the horizontal and vertical velocity. Performance objective sin projecting objects: maximum vertical distance (dvert, maximum vertical distance with some horizontal, maximum horizontal distance (dhori) Greater v of projectile = greater force of drag fdrag. On descent, acceleration influenced by gravity and air friction but lets just neglect air friction for now. Could be higher or less in some cases. What matters in sports with different objectives. Maximum vvertical: height of c of g at takeoff point, vvert of c of g at takeoff (greater = higher, location of body segments @ apex. Using arms to help with max vertical height. Tumbling jumps reaching great heights while moving from.
