Successive body segments move in combination and the distal segment is free to move in space. Angular momentum generated in massive proximal segments. Angular velocity maximised at less massive distal segments. Describe the different throwing mechanics as they relate to the performance objectives of a darts throw and a baseball pitch. The use of multiple long segments can improve throwing velocity but reduce accuracy. Shaft length of golf clubs related to shot distance. Longer club = greater linear club speed for same angular speed; same for longer body segments. Pga tour bubba watson club head speeds 2010. Greater r same still = greater s.
