In this movie, uniform circular motion (i.e. circular
motion at constant speed) is assumed for simplicity.
Various objects are set into circular motion. In
each case, it is shown that a centripetal force is required to
maintain circular motion. The agent which supplies that net force
toward the center is discussed and demonstrated.
