	Exerting a force over some distance represents a specific transfer of [[energy]] also known as [[work]].

San Francisco, U.S.A.: Pearson Addison-Wesley, 2008, pp. 806</ref> The position of objects within these fields determine an object's [[potential energy]]. When an object is pushed into against the force of one of these fields, the object gains potential energy. An object that moves along the push of theses fields loses potential energy and gains [[kinetic energy]] (or [[thermal energy]]). Forces exchanging energy between potential and kinetic energy is an example of [[mechanical energy]] conservation (if thermal energy is increased then there's still [[conservation of energy\|energy conservation]], but it's trickier).
