摘要
水平面直线上若干个物块的弹性碰撞次数问题常见于各类物理竞赛。本文通过例证说明,运用基于动量守恒定律和能量守恒定律的图像法求解相关的一维弹性碰撞次数问题,不但可行而且有利于简化分析过程,具有直观清晰的特点。
The problem of the number of elastic collisions of several blocks on the horizontal plane is common in various physical competitions.In this paper,it is illustrated by examples that using the graphic method based on the law of conservation of momentum and the law of conservation of energy to solve the related one-dimensional elastic collision number problem is not only feasible but also beneficial to simplify the analysis process,and has the advantage of intuition and clarity.
