二维弹性碰撞与动量关系的几何研究

Research about the relation between two-dimensional elastic collision and momentun in geometry

从质心坐标系出发,利用粒子动量关系的几何描述,直观形象地研究了两粒子二维弹性碰撞的各种情况.

Based on the research of centerofmass frame of coordinate,and by using the geometrical description of the momentun of particle,the twodimeusional elastic collision between two particles in different conditions is studed.
