摘要: 讨论了小球与定轴转动杆碰撞过程中所遵从的物理规律,进一步明确了完全非弹性碰撞过程的能量特征,指出完全非弹性碰撞后两物体不一定粘在一起共同运动的事实.

关键词: 完全弹性碰撞, 完全非弹性碰撞, 旋转, 动能最小可能值

Abstract: The physical rule of the collision of a pellet and a fixed-spindle pole is discussed and the energetic characteristics of complete inelastic collision is clarified.Finally,we prove that two objects will not move together side by side necessarily after a complete inelastic collision.

Key words: complete elastic collision, complete inelastic collision, rotation, minimum value of kinetic energy
