Conservative forces and potential energy
... In section 7–2 of your textbook the oscillatory motion of a mass attached to a spring is described in the context of energy conservation. Specifically, if the spring is initially compressed then the system has spring potential energy. When the mass is free to move, this potential energy is converted ...

PS Energy and Work
... Energy is necessary to supply the force to do work. In fact, the definition of energy is “the ability to do work.” Energy can be classified a two distinct types; potential and kinetic. Potential energy is stored energy. There are three (3) distinct types of potential energy; chemical potential energ ...
