what does mechanical energy mean
In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.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.n example of a mechanical system: A satellite is orbiting the Earth only influenced by the conservative gravitational force and the mechanical energy is therefore conserved. The satellite is accelerated towards the Earth with an acceleration perpendicular to the velocity.
