机械能守恒定律遵从力学相对性原理

摘要

In this paper it is explained that the law of conservation of mechanical energy must obey the relativity principle of mechanics.If the mechamical energy does not change in an inertial system,the in any reference frame it is also constant.%文章系统地阐明了机械能守恒定律无条件服从力学相对性原理.若总机械能在一个惯性系守恒，它就在所有惯性系守恒.
