Experimental and theoretical results are presented showing that a ball with a high coefficient of
rolling friction can roll to a stop when it rolls without slipping down an inclined plane. The rate
at which energy is dissipated is directly proportional to the rolling friction force on the ball,
despite the fact that the net work done by the friction force is zero. The energy loss arises from
internal friction within the ball due to compression and expansion of the ball in the contact
region. Since the compression force is larger than the expansion force, an opposing torque arises
that reduces the angular velocity of the ball. The work done by the opposing torque is equal to the
energy that is dissipated.
