Once more about "the collision of particle and a homogeneous free bar"

  • Online:2007-09-25 Published:2007-09-20

摘要: 讨论了小球在杆上任一点的碰撞问题,并指出《大学物理》2006年第5期《小球与均质自由杆的碰撞》一文中“完全非弹性碰撞后两物体不一定粘在一起共同运动”的说法是错误的.

关键词: 动量, 角动量, 完全弹性碰撞, 完全非弹性碰撞, 能量最小值

Abstract: The physical rule of the collision of a particle and a free bar at any point is discussed, and "the two bodies not necessarilly move together after completely inelastic collision" is pointed out to be wrong.

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