两体问题的研究对象有两个物体,两段问题的物理过程有两个阶段,两体两段问题,是一种基本的综合题,因为这类问题,既能巩固基本概念,又能培养多种能力,其解题思路又是解决难度大的综合题的基础。最近几年物理高考题中属于这类题的也较多,本文谈几点教学中的做法,仅供参考。 The research object of the two-body problem has two objects. The physical process of the two-stage problem has two stages. The two-body and two-stage problems are a basic comprehensive problem. Because such problems can not only consolidate the basic concepts, but also cultivate Many kinds of abilities, their problem-solving ideas are the basis for solving difficult problems. In recent years, the physics college entrance examination questions are also more of this kind of questions. This article discusses some of the practices in teaching and is for reference only.
