8.4 Conservation of Energy Part II
... Energy is neither created nor destroyed. It may only be transformed from one type to another. This means that if we are looking at a closed system (a situation that has no outside sources of energy), the total amount of energy at the start and the total amount of energy at the end must be the same. ...
