图象具有简明、直观等特点,用图象来研究物理现象、描述物理规律是物理学中常用的一种重要方法。图象中最典型的是运动图象,它是学习其它图象的基础,主要有x-t图象和v-t图象,它们能形象直观地反映出物体的运动情况,图线的上的点、线段、截距、斜率及与t轴所围的面积等都有明确的含义。本文将通过例题分析引导学生巧用图象法处理运动学问题。 The image has the characteristics of conciseness and intuition. The study of the physical phenomena by imagery and the description of the physical laws are an important method commonly used in physics. The most typical image is a moving image, which is the basis for learning other images, there are xt images and vt images, they can visually reflect the object’s movement, the point on the map lines, line segments , Intercept, slope, and the area enclosed by the t-axis have a clear meaning. This article will guide students through the example analysis to cleverly use the image method to deal with the kinematics problem.
