Which of the following energy change involves frictional force?
(a) chemical energy to heat energy
(b) kinetic energy to heat energy
(c) potential energy to sound energy
(d) chemical energy to kinetic energy
Frictional force is responsible for heating up of the tires of a moving vehicle. In such a situation, kinetic energy is converted into heat energy due to the frictional force.
Therefore the answer is,
(b) Kinetic energy to heat energy.
