普通高中实施新一轮的课程改革以来,高中物理教材有所改变,大纲也在改变,但基本概念、基本规律和基本解题思路不会变,它们仍然是高考物理考查的主要内容和重点内容。结合高中物理新课改理念,本人在高考复习中,归纳出了一些结论,灵活应用这些结论,可使解题过程大为简化,现以滑动摩擦力的计算举例说明。滑动摩擦力大小可以用胡克定律f=μFN来计算,其中动摩擦因数μ由接触面的材料和粗糙程度决定,对于同一接触面μ不变,
Since the implementation of the new round of curriculum reform in ordinary senior high schools, there has been a change in high school physics teaching materials and the outline has also changed. However, the basic concepts, basic rules and basic solutions to problems have not changed. They are still the main contents and key contents of the physical examination of college entrance examination . Combined with the new curriculum reform concept of high school physics, I summarize some conclusions in college entrance examination review. The flexible application of these conclusions can greatly simplify the process of solving problems. The example of sliding friction calculation is given as an example. The size of sliding friction can be calculated by Hooke’s law f = μFN, where the dynamic friction coefficient μ is determined by the material and roughness of the contact surface, and μ is the same for the same contact surface.
