Turns out, some of these equations were very familiar: the lawof conservation of momentum, and Newton'ssecondlawofmotion.
其结果,其中一些方程非常眼熟,比如动量守恒定律和牛顿第二定律。

It follows from the principle of relativity that Newton'ssecondlawofmotion, although fundamental in classical mechanics, only has an approximate and by no means complete validity.
由相对论原理可知,牛顿运动第二定律尽管是古典力学中的基本原理,但只是近似的,而绝不是完全正确的。
