WebThe force exerted back by the spring is known as Hooke's law. \vec F_s= -k \vec x F s = −kx. Where F_s F s is the force exerted by the spring, x x is the displacement relative to the unstretched length of the spring, and k k is the spring constant. The spring force is called a restoring force because the force exerted by the spring is always ...
