在中学物理中,整体法是物理学中重要的一种思想方法,整体法不仅是中学物理教学中常见的方法,而且也是解决物理问题的一种重要方法,然而,在教学中教师很多时候只灌输给学生如何应用整体法,而并没有把它的来龙去脉分析给学生,学生在分析复杂的物理问题(特别是加速度不同的连接体问题)时常感到不能理解和灵活应用,从而影响了用整体法对问题的求解.下面笔者就从简单的两个物体组成的连接体问题来 In middle school physics, the holistic law is an important method of thinking in physics. The holistic approach is not only a common method in physics teaching in middle schools, but also an important method to solve physical problems. However, in teaching, teachers often only Instilling in the students how to apply the whole law, but did not analyze its ins and outs to the students, students often feel incomprehensible and flexible application in the analysis of complex physical problems (especially the acceleration of different connectors), thus affecting the use of the whole law Solve the problem. The following author from the simple connection between the two objects to the problem
