the conservation of momentum 动量守恒
Conservation of momentum equation 动量守恒方程为
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。
Okay, conservation of momentum.
下一个，动量守恒。
So the conservation of momentum tells you what the speed is after the collision.
动量守恒定律告诉你,碰撞后速度是多少。
