Two balls with the same mass, one of wood and the other a Ping-Pong ball partly
filled with sand, are rolled along a desk. The wooden ball rolls along nicely, but the
Ping-Pong ball stops in a few centimeters. What happened to its kinetic energy?
Was the kinetic energy changed to heat energy by the force of friction between the
ball and the desk? Explain your answer.
