With the relationship of the system linear and angular momentum conservation, a system dynamics model was established by Lagrangian formulation.

结合系统线动量及角动量守恒关系，通过拉格朗日法建立了系统的动力学模型。

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。

This is because of conservation of angular momentum, the same property that causes ice skaters to spin faster if they draw their arms in.
