Work Energy & Power
Work, energy and power Work, energy and power are words used frequently in everyday life. However, in science (and physics in particular) we need careful definitions which sometimes conflict with everyday usage. Work Work is done when a force moves an object on which it is acting in the direction of the force. We define work formally as follows: Work is done when force F moves its point of application in such a way that some resolved part of the displacement vector s lies along the dire...
