如何准确迅速地求出两个物体发生弹性碰撞后的速度 ,在高中是一个非常棘手的问题 .笔者在长期的教学实践中探索出了三种方法 ,简介如下 :一、利用韦达定理法题目 两物体 m1、m2 分别以速度 v10 、v2 0 在光滑水平面上发生对心弹性碰撞 ,求碰撞后两物体的速度v1t、v2 t?分析与
How to accurately and quickly determine the speed of elastic collision between two objects is a very difficult problem in high school. The author has explored three methods in the long-term teaching practice. The brief introduction is as follows: First, the use of Vedic theorem topics The two objects m1 and m2 collide elastically at velocity v10 and v2 0 on a smooth surface. The velocity v1t and v2 t? of the two objects after collision are analyzed and analyzed.
