Elastic potential energy in a spring, computer illustration. Elastic potential energy is the energy stored as a result of deformation of an elastic object, for example the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the displacement of the spring (x) and the spring constant, a characteristic of the spring. Hooke's law states that the displacement of the spring (x) is proportional to the force acting on it (red arrow).
