Document Summary

Proximal segments are in front of the projectile, and distal segments are behind the. Is used to create an increased velocity in a throw pattern. Uses a wheel-axle motion to project something in a curvi-linear path. Open: a process using all muscles from large to small sequentially projectile. Closed: a process using all muscles simultaneously. L = iw angular momentum = rotational inertia x angular velocity. Is used to create an increased force in a push pattern. Uses mainly lever motions to project something in a recti-linear path. I is calculated in the same way as explained before (i = mk2) Once angular momentum is established (ex: the push off), it remains constant. When you bring your arms closer to your body, you decrease the k value, which in turn. However, when you decrease the i value, you increase the w (angular velocity) As a result, when spinning you are increasing or decreasing angular velocity not angular.
