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。
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.
不知怎么的，这一定律和,角动量守恒定律有所相似。
Somehow, it has the smell of some conservation of angular momentum.
动量守恒定律告诉你,碰撞后速度是多少。
So the conservation of momentum tells you what the speed is after the collision.
