What is Energy?

Energy is the amount of work an object can do or is doing, usually measured in joules. Energy cannot be destroyed nor created, only changed or transferred, in an isolated system. This is known as the law of conservation of energy, which is the first law of thermodynamics, which along with two other laws explain the relationship between heat and other energy. It also explains how energy can be lost through heat.
