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