The force that causes simple harmonic motion. The restoring force is always directed toward an objectâ€(tm)s equilibrium position.
A force that acts to return an object to its equilibrium shape. A restoring force is directed toward the position the object occupies when it's in its equilibrium shape.
A force caused by the coupling's resistance to displacement.
the force exerted by a spring when it is stretched or compressed, which tends to restore the spring to its resting length.
a force which acts in a direction opposite the direction of the displacement from the equilibrium position
Restoring force, in a physics context, is a variable force that gives rise to an equilibrium in a physical system. If the system be perturbed away from the equilibrium, the restoring force will tend to bring the system back toward equilibrium.
