Detailed Solution

The above statement is False.
When two surfaces come closer, that too moving produces friction, and some kinetic energy is transformed into heat energy. Friction can sometimes be useful. Friction is an everyday force that is produced when two surfaces interact with each other. When these surfaces slide against each other, this interaction increases the thermal energy of the two surfaces, and the temperature rises.
The energy used to overcome the frictional force mainly results in high temperature. Therefore, heat energy is the main energy used to overcome friction.
The correct statement would be that friction is overcome by heat energy only.
