What are the sources of mechanical energy?

Falling water (ultimately from the water cycle). Tidal action or wind (ultimately from Earth's rotation). Wind generated from solar heated soil (some caves breathe in at night, and out in the morning). read more

Mechanical energy. 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. read more
