在完全弹性碰撞中,动量守恒,动能也守恒,根据两个守恒关系,可列出二元二次方程组,以达到解决问题的目的.本文探讨一种不必列出二次方程组的一种方法,用该方法可以很方便地解决弹性碰撞的有关问题.图1首先,我们将两个做弹性碰撞的物体等效成图1所示.置于光滑水平面上的A、B两个 In the fully elastic collision, the momentum is conserved and the kinetic energy is also conserved. According to the two conservation relations, the binary quadratic equations can be listed to solve the problem. This article discusses a method that does not need to list the quadratic equations. The method can be used to easily solve the problems related to elastic collisions. Figure 1 First of all, we equate two elastic collision objects as shown in Figure 1. A and B are placed on a smooth horizontal surface.
