Question

Which of the following energy change involves frcitional 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

Solution

B) kinetic energy to heat energy.
due to frictional force, the objects which are in motion stop. As they possess kinetic energy, objects come in contact with each other which generates heat energy between them.
