关于碰撞过程中动量与能量的守恒问题的讨论

Discussion on the Conservation of Momentum and Energy in Collision

基于碰撞过程中的能量转换,对碰撞过程中的动量守恒和能量守恒进行了讨论,并给出了非弹性碰撞过程中能量转换的计算,以及碰撞规律在质心坐标系和实验室坐标系中的关系,以期对学生学习碰撞的有关物理问题提供有益的启发.

Based on the energy conversion in the collision process, the conservation of momentum and energy in the collision process are discussed in this paper. The calculation of energy conversion in the inelastic collision process and the relationship between the collision law and the centroid coordinate system and the laboratory coordinate system are given. In order to provide useful enlightenment for students to study collision related physical problems.
