Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses...

Learn the mechanical energy definition and characteristics and how mechanical energy compares to kinetic and potential energy. See mechanical energy examples. Updated: 11/21/2023 Mechanical Energy Definition The definition of energy in physics is the capability to perform work or to cause motion or...
In all of these examples, the kinetic energy evolves from a conversion from some other form of energy. The force behind the movement of a piston comes from an expanding gas produced by the ignition of a gasoline/air mixture. The kinetic energy acquired by water rushing to the bottom of a...
