    in a condition that work may be recovered from it. Thus, when a spring is bent, or weight raised, and is in a posi- tion to act, potential energy is acquired by the work done in bending the spring or in raising the weight. Potential becomes actual or kinetic energy when the spring or weight is released to move some other body, or to do work of some kind. Difference of potential between any two points is the work done in carrying a unit of mass from one point to the other. Zero potential is the point chosen as a standard of reference. Any place which requires work to be done to bring the unit of mass from the zero point to it will have positive potential, and any place which requires work to be done to bring the unit of mass from it to the zero point has negative potential.
