物理学中,“碰撞”是指通过相互作用,动量发生显著变化的过程。一般情况下,碰撞过程会有动能上的损失,而碰后物体“结合”在一起的情形,动能损失最大,这种碰撞就是“完全非弹性碰撞”。此类问题中涉及多个物体的相互作用,过程抽象、复杂。它的物理过程、运动状态变化及能量转化关系的分析处理,对学生的理解能力、逻辑思维能力及分析推理能力等方面有着全面的考量功能。
In physics, “collision” refers to the process by which the momentum changes significantly through interaction. Under normal circumstances, the collision process will have kinetic energy losses, and after the collision of objects “combination ” together, the kinetic energy loss, the collision is “completely inelastic collision ”. The interaction between multiple objects involved in such problems is abstract and complicated. Its physical processes, changes in the state of movement and the relationship between energy conversion analysis, students’ ability to understand, logical thinking and analytical reasoning ability has a comprehensive consideration.
