<P> Another example is of a pendulum . When the pendulum is not swinging all the forces acting on the pendulum are in equilibrium . The force due to gravity and the mass of the object at the end of the pendulum is equal to the tension in the string holding that object up . When a pendulum is put in motion the place of equilibrium is at the bottom of the swing , the place where the pendulum rests . When the pendulum is at the top of its swing the force bringing the pendulum back down to this midpoint is gravity . As a result gravity can be seen as the restoring force in this . Restoring force of a spring : ( f = - kx ) </P>
