摘要
从能量的角度对碰撞的三种过程进行分析和讨论。完全弹性碰撞过程动能守恒,完全非弹性碰撞和非完全弹性碰撞过程动能均有损失,且前者动能损失最大。
The three processes of collision were analyzed and discussed from ener- getic standpoint.The kinetic energy of the process of complete collision conserves,that of the processes of complete inelastic collision and incomplete elastic collision are all more or less lost,and the loss of the former's kinetic energy is the most.
