有关摩擦力的问题,一直是学生学习的难点.在教学中发现,如果物体受力较少,物理情景较简单,学生能顺利解决有关摩擦力的问题,但一遇到受力较多,情景较复杂时,不知如何分析摩擦力.究其原因学生对摩擦力的相关基本概念没有深入理解.本文以高三学生在复习摩擦力过程中出现的问题为出发点,从摩擦力的产生条件及其三要素入手[1],使学生深入理解摩擦力,学会解决有关摩擦力的综合问题.
The problem of friction has always been a difficult point for students to learn.It has been found in teaching that if the subject is less stressed and the physical situation is simpler, the student can successfully solve the problem of friction, but once he experiences more stress, The more complex, I do not know how to analyze the friction force.The reason for the students do not have a deep understanding of the basic concepts related to friction.In this paper, the high school students in the process of reviewing friction problems as the starting point, from the frictional conditions and three Elements to start [1], so that students in-depth understanding of friction, learn to solve the comprehensive problem of friction.
