能够直观、形象揭示两个物理量变化依赖关系的物理图象,对深刻理解概念,牢固掌握规律具有其他任何形式都不能替代的作用,同时因为图象还有特殊的意义,譬如它的图线(直线)的截距、斜率及与横轴所围成的面积都含有鲜明的一目了然的物理内容,所以它又能帮助我们提高解题能力和技巧,甚至能够解决利用通常的计算方法在中学阶段尚无法解决的问题。下面就利用图象解答物理习题作一些分析和探讨。
A physical image that can intuitively and visually reveal the dependence of the two physical quantities on the concept of deep understanding of the concept and the ability to firmly grasp the law has no substitute for any other form, and because the image has special meaning, such as its graph ( The intercept, slope of the straight line, and the area enclosed by the horizontal axis all contain a clear physical content, so it can help us improve problem-solving abilities and skills, and can even solve the problem of using the usual calculation method in middle school. Unsolvable problem. The following uses the image to solve the physical exercises for some analysis and discussion.
