Hooke's law states that the force exerted by a stretched or compressed spring is a restoring force and is linearly proportional to the distance that the spring is stretched or compressed beyond it's relaxed length. The formula for Hooke's law is <math> \vec F = -k \vec x </math> where k is the spring stiffness constant which has units of newtons per meter and <math> \vec x </math> is the displacement from the equilibrium position.
