高中物理教材中的知识点都是以单个物体为研究对象,但在运用过程中往往会同时分遇到多个物体,很多老师教同学将每个物体分隔开来分析,也就是所谓的隔离法,但往往分析起来较复杂,计算量大,容易出错。笔者认为可以将多个物体整体分析,这就是整体法,即对物理问题的整个系统或整个过程进行研究的方 High school physics textbook knowledge points are based on a single object for the study, but in the course of the application will often encounter multiple objects at the same time, many teachers teach students to separate each object for analysis, which is the so-called isolation Act, but often more complicated to analyze, large amount of calculation, error-prone. I believe that the overall analysis of multiple objects, which is the whole law, that is, the entire system of physical problems or the entire process of research
