摘要
用相关的物理知识解决二维碰撞的问题,发现碰撞中更为普遍的规律.对于二维完全弹性碰撞问题,可以用矢量分解、能量守恒和动量守恒解决.
The Collision is a common phenomenon in our life,and it is important for classical physics,as well as it is the core content in the momentum. The first law of conservation momentum was found in order to solve the problem of collision. We have learnt the central collision in the high school and comprehended the great charm of momentum. In this article,we use the relevant physical knowledge to solve the two- dimensional collision problem,and find the more general regular in collision. As for the problem of two - dimensional perfect elastic collision,the vector decomposition,energy conservation and momentum conservation can be used to solve it.
