能量守恒定律 能量守恒定律阐明能量既不能被创造,也不能消灭, 它只能从一种形式转换成另一种形式,或从一个系统 转移到另一个系统,而其总量保持恒定 Conservation of energy principle states that energy can be neither created nor destroyed; it can only change from one form to another but the total amount off energy remains constant.能量守恒定律阐明能量既不能被创造，也不能消灭， 它只能从一种形式转换成另一种形式，或从一个系统 转移到另一个系统，而其总量保持恒定。 Conservation of energy principle states that energy can be neither created nor destroyed; it can only change from one form to another but the total amount of energy remains constant. 能量守恒定律
