| 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. |

| Keywords: | complete elastic collision complete inelastic collision rotation minimum value of kinetic energy |
