Question

what is the definition of restoring force?

Answer 1

Restoring force, in a physics context, is a forcethat gives rise to an equilibrium in a physical system. If the system is perturbed away from the equilibrium, the restoring force will tend to bring the system back toward equilibrium. Therestoring force is a function only of position of the mass or particle.

A force which causes an object to regain its stable state of equilibrium is known as restoring force. If the system is perturbed away from the equilibrium, the restoring force will tend to bring the system back toward equilibrium.

For example the resistance of a spring when it is extended is a restoring force.
