For example, no matter how much a dancer wishes to leap off the floor and then start turning, the law of conservation of angular momentum absolutely prevents such a movement.
例如,无论一个舞者多么想要跳离地板,然后开始旋转,角动量守恒定律绝对阻止这样的动作。
He is adamant that this is not a perpetual motion machine, and does not violate the law of conservation of momentum because different reference frames apply to the drive and the waves within it.
他坚持认为这并非永动机,也没有违反能量守恒定律,因为驱动器和里面的微波使用不同的坐标系。
Turns out, some of these equations were very familiar: the law of conservation of momentum, and Newton's second law of motion.
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。
