Springs (from French: ressort) are elastic bodies used in mechanical systems. Springs are divided into two types:

deformed at willhave the power to revive at willSprings usually have one equilibrium position at rest (no external force is applied), but springs also have many rest positions. Theoretically springs convert all the power of the external force upon impact into elastic potential energy, and release all this potential energy back to mechanical success in the absence of the external force. In fact, there is no such spring. Springs actually always expend some of the external power into heat or other energy that cannot be recovered.
