关于弹性碰撞过程中动量守恒问题的讨论

On conservation of momentum in elastic collision process

在简要讨论碰撞过程机理的基础上 ,仔细分析了引起系统动量和能量变化的因素。探讨了弹性碰撞的实质和特征 ;重申了动量守恒的条件 ,进而指出 :弹性碰撞过程中动量不一定守恒 。

Based on a brief discussion about collision process mechanism,this paper analyses concisely fuctors wihch alter momentum and energy.The parenchyma and character of elastic collision are investigated and the conditions of conservation of momentum are not necessary for conservation in elastic collision process to define elastic sollision as one which motive energy and momentum are all conservation for is not advisvable.This view is ready for teachers in physical teaching to refer to.
