Answer 1

In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. 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.

Answer 2

Energy that moves things. Think of your arm grabbing a glass of water. That's a form of mechanical energy because you just moved something.
