The law of conservation of energy states that in any physical, chemical or nuclear process, energy cannot be created or destroyed but can only be transformed from one form to another. Energy can be transformed from one form to another but the total amount of all the energies of the universe always remains the same. This is called the principle of conservation of energy. Let's test yourself about the Principle of Conservation of Energy trivia quiz.
