Document Summary

Transfer l to arm by reducing / stopping l in shoulders: The contralateral arm is used to stop the shoulders from rotating. The stopping of movements in the larger body parts transfers their angular momentum to smaller body parts. Next event (movement of smaller parts) begins as previous event (movement of larger parts) is still occurring. To maintain the angular momentum created by the larger body parts, smaller parts must increase their velocity. The higher the tennis racquet hits the ball, the increased margin of error. This means that there are more angles in which one can hit the ball into the service box successfully. Smaller / lighter projectiles allow more segments to contribute to the performance. Smaller / lighter projectiles allow for a greater k. Smaller / lighter projectiles allow smaller segments to give the greatest contribution (ex: badminton vs. tennis) Larger / heavier project get the greatest contribution from larger body segments.
