物理习题的解答,有一定的特殊规律性,根据物理学研究内容及其特点,大致可按以下步骤进行:首先是弄清楚研究的对象;其次是分析物理过程;接下来是选择有关物理知识;然后是列式计算求解;最后是检验答案和总结经验。这几个环节都非常重要,其中分析物理过程是学生解题时的薄弱环节。因此,在教学中,我注重了对学生在这一方面的指导。 例如,教材中有这样一道习题“骑自行车的人以 The answers to physical exercises have certain special regularities. According to the research content and characteristics of physics, the following steps can be roughly carried out: firstly, to clarify the research object; secondly, to analyze the physical process; and then to select relevant physical knowledge; Then there is a columnar computational solution; the final one is to test the answers and summarize the experience. These three aspects are all very important, and the analysis of physical processes is a weak link for students to solve problems. Therefore, in teaching, I focused on the guidance of students in this area. For example, there is such an exercise in the textbook "Bicyclist
