Chapter 12.1, Problem 12SSC

To determine

The mechanical energy and the thermal energy of bouncing basketball.

Explanation of Solution

Introduction:

The temperature is the measure of sum of kinetic energies of all the molecules of an object.

The mechanical energy is sum of kinetic and potential energy of an object.

The bouncing ball has mechanical energy which is sum of potential and kinetic energies of whole mass. The thermal energy is the sum of measure of kinetic and potential energies of individual particles of a ball.When the ball hits the ground,heat will be transferred to the ball due to vibration of molecules.

Conclusion:

The mechanical energy and thermal energy of a ball is conserved during bouncing of a ball.
