正确分析和解决局部与整体的关系是物理教学中常用的处理问题的方法。一、研究力学问题要运用“隔离法”的观点来分析局部与整体的关系力学中用“隔离法”解题,就是正确分析和处理局部与整体的关系。所谓“隔离法”就是想象地从连接体中“隔离”出所要研究的某一个物体(或某一部分物体),然后单独分析“隔离体”的受力情况。在此基础上还要把它受到的所有
Correctly analyzing and resolving the relationship between the local and the whole is a commonly used method to deal with problems in physics teaching. First, the study of mechanical problems to use the “isolation method” point of view to analyze the relationship between the local and the overall use of “Isolation” to solve problems, is the correct analysis and treatment of the relationship between the local and the whole. The so-called “isolation method” is to imaginarily “isolated” an object (or a certain part of an object) to be studied from the connector, and then separately analyze the force condition of the “isolator”. On this basis, we must also take it all
