# Mechanical Energy

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Mechanical energy, abbreviated as ME, is the sum of the change in kinetic energy and potential energy generating from the force of gravity, external forces or the movement released in machine movement.  The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces, the mechanical energy is constant.

 $$\large{ ME = PE + KE }$$          Where: $$\large{ ME }$$ = mechanical energy $$\large{ KE }$$ = kinetic energy $$\large{ PE }$$ = potential energy
