CORRECTION: THE FBDs SHOULD SHOW THE GRAVITY FORCE IN THE J-HAT DIRECTION.  THIS IS A TYPOGRAPHICAL ERROR, AND DOES NOT AFFECT ANY CALCULATIONS.

In this video, I compare a rigid body pendulum with a point mass pendulum, to more fully explore the effects of rigid body rotation.  This is a continuation of the previous two videos on rigid body rotation, 15.4-01 & 15.4-02.
