固体和液体压强的计算是初中物理的重点和难点,在教学的过程中发现很多学生由于方法使用不当造成了很多不必要的错误,正确掌握方法对解决这类问题至关重要.下面结合自己的教学经历,谈谈这类问题的解法,希望对同学们有所帮助.计算压强时一定要先认清是固体还是液体的压强计算.若是固体(且往往都放在水平面上),则先利用F=G求出 The calculation of solid and liquid pressure is the focus and difficulty of junior high school physics. During the teaching process, many students find many unnecessary mistakes due to improper use of methods. It is very important to correctly grasp the methods to solve such problems. Teaching experience, talk about the solution of such problems, I hope to help students.Calculation of pressure must first identify the solid or liquid pressure calculation.If the solid (and often on the level), the first use of F = G
