Elastic energy
OverviewElastic potential energy in mechanical systemsContinuum systemsSee alsoSources
Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner. Elasticity theory primarily develops formalisms for the mechanics of solid bodies and materials. (Note however, the work done by a stretched rubber band is not an example of elasti…

Energy Storage and Transfer: Elastic Energy
We say that the stretched rubber band or compressed spring stores elastic energy—the energy account used to describe how an object stores energy when it undergoes a reversible deformation. This energy can be transferred to another object to produce a change—for example, when the spring is released, it can launch a dart.
