The Free Rotation model shows the torque-free motion of a rectangular block. The model displays a space frame view showing a constant angular momentum arrow and a body group containing a block and body-axis arrows. This model is designed for the study of torque-free precession. The tips of the body frame axis arrows trace trajectories to illustrate stable and unstable rotation of the block about a principal axes. A second window displays the body frame view with space frame xyz-axes orbiting the block.
