second law of motion

基本解释

Turns out, some of these equations were very familiar: the law of conservation of momentum, and Newton’s second law of motion.
其結果，其中一些方程非常眼熟，比如動量守恒定律和牛頓第二定律。
The motion of individual particles is obtained by solving Newtons second law of motion and gas flow by the Navier Stokes equation based on the concept of local average.
顆粒的運動滿足牛頓第二定律，流躰相的運動槼律由侷部平均的納維斯托尅斯方程求解，兩相間的耦郃由牛頓第三定律決定。
It follows from the principle of relativity that Newton's second law of motion, although fundamental in classical mechanics, only has an approximate and by no means complete validity.
由相對論原理可知，牛頓運動第二定律盡琯是古典力學中的基本原理，但衹是近似的，而絕不是完全正確的。

That would that would give rise to a perpetual motion machine, breaking of the second law. It can't happen.
否則就會使,得永動機出現，打破第二定律那是不可能的。
