关于碰撞过程中动量变化规律的讨论

Discussion on the Law of Momentum Change in the Cource of Collision

对碰撞过程中的动量及其变化规律进行了讨论 .检验了动量定理和动量守恒定律在碰撞的瞬时过程里也处处成立 定性画出了碰撞中动量随时间变化的P -t曲线 .

In the paper the writer has discussed the momentum in the course of collision and its law of changes, checked up the momentum theoren and the law of conservation of momentum in the momentary course of collision and drawn its momentum p-t curve along with the change of time.
