(physics) The sum of the potential energy and kinetic energy of a body or system

An example of a mechanical system: The only force acting on a satellite orbiting the Earth is its own weight; its mechanical energy is therefore conserved. The satellite's acceleration is represented by the green vector and its velocity is represented by the red vector. The potential energy of the satellite, and its kinetic energy, may vary with time but their sum remains constant.
