利用图解法分析物理现象,应该看做是物理教学进行中一个重要的组成部分.因为教师用图解来分析阐明,既容易讲明讲透物理现象,又可以启发学生怎样掌握辩证的观点来分析问题,有利于学习和巩固.借用图解法,通过分析阐明之后,再结合公式提出重点,要求学生牢记也比较容易.学生往往由此在脑里刻划着一幅描绘的图画.此后,在任何适当的场合下, The use of graphic methods to analyze physical phenomena should be seen as an important part of physics teaching. Because teachers use diagrams to analyze and clarify, it is not only easy to explain the physics phenomenon, but also to inspire students how to grasp the dialectical point of view to analyze problems. It is conducive to learning and consolidating. By borrowing graphic methods, through analysis and clarification, and combining formulas to put emphasis on, it is also easier for students to keep in mind. Students often draw a picture depicting this in their brains. Thereafter, in any appropriate Occasions,
