利用图象解题,是学习高中物理的重要方法。图象能形象直观地反映题目意思,还能从图象中得出相关规律或结论,如利用速度-时间(v-t)图象、位移-时间(x-t)图象解题。相当一部分试题转换角度,画出最贴近该题题意的图象,能带来意想不到的直观和快捷。举几个实例说明。例1.在一水平向右匀速传输传送带左端A点,每隔T时间,轻放上一个相同的工件,工件与传送带间动摩擦因素为μ,工件质量均为m,经测量,已经和传送带达到相同速度工件之间距离x,
The use of image problem solving is an important way to learn physics in high school. The image can vividly reflect the meaning of the topic, and the related laws or conclusions can be drawn from the image, such as using the speed-time (v-t) image and the displacement-time (x-t) image solution. A considerable part of the test conversion point of view, draw the image closest to the title of the question, can bring unexpected and intuitive. Cite a few examples. Example 1. At a horizontal left and right conveyor belt A point A, every T time, put a light on the same workpiece, the friction factor between the workpiece and the conveyor belt μ, the quality of the workpiece are m, measured and the conveyor belt has been reached The same speed between the workpiece distance x,
