Rotational Dynamics

To illustrate the role of centripetal force in rotational motion.

Rotation apparatus with various attachments (clear glass bulb, circular brass bands, sliding weights, closed tube for bouyancy).

Examine the behavior of the different attachments under rotation. Discuss centipetal and centrifugal forces. A broken centrifuge is also available (courtesy of Dr. J. Beams) to illustrate the results of inadequate centripetal force in an object undergoing extremely high rotational velocities.
