Answer 2

Answer:

With the exceptionof energy and fuels (such as kerosene oil, coal, etc., or the energy in cells and battery), all forms of kinetic energy and potential energy taken together, form mechanical energy Muscular energy of all kinds of animals is also a kind of mechanical energy. In generating this energy, chemical energy of the food is utilised. It is released in the form of form of heat energy.
