Work is defined as an attempt to move an object by a distance S (m) with a force F (Newton).
With the energy of all things can happen. The sun shines is the energy that makes plants can live and thrive, the energy contained in food can make us move and maintain the body temperature to keep warm, and energy in the fuel the engine
