摘要: 讨论了小球与自由杆碰撞过程中所遵从的物理规律,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 particle and a bar is discussed, the energy relation in completely inelastic collision is cleared, and it is turned out that the two bodies not necessarilly move together after completely inelastic collision.

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