摘要: 在Cowley等的子弹和木块碰撞实验的基础上分析了能量守恒、动量守恒以及角动量守恒的应用环境,展示了质点和刚体相互作用特征.

关键词: 质点, 刚体, 碰撞

Abstract: Based on the experiments of bullet-block collisions, the applicable conditions of energy conserva- tion, momentum conservation, and angular momentum conservation are analyzed. The collisions of bullet-block can be simplified as the interaction between a material particle and a rigid body. Therefore, the experimental phenomena show some features of this interaction.

Key words: material particle, rigid body, collision
