Throw a tennis ball or baseball for distance:
a. standing still, facing in the direction of the throw.
b. standing with the left side toward the direction of the throw, with the feet apart and the weight evenly distributed, using a full arm swing and body twist with the throw.
c. same as in b, except with the weight on the right foot to begin with, shifting to the left as the ball is thrown.
Compare the three methods for distance. Explain in terms of length of backswing, speed at moment of release, and total distance used in applying force to ball before releasing it.
