压强知识是初中物理的重要组成部分,有关压强的命题涉及知识点多、综合性强、能力要求高.同学们在解这类题时错误百出,究其原因,除了对压强概念理解不深不透外,主要是解题思路和方法不对头.为帮助同学们掌握这类题的解题思路和方法,现例析如下.
Pressure knowledge is an important part of junior high school physics. Propositions related to pressure involve many knowledge points, strong comprehensiveness, and high ability requirements. The students are riddled with errors in solving such questions. The reason is not to understand the concept of pressure. Throughout, it is mainly to solve problem-solving ideas and methods are not correct. To help students master the problem-solving ideas and methods of such questions, examples are as follows.
