一、位移—时间图像(s-t图像)1.图像意义以纵轴表示位移,以横轴表示时间而做出的反映物体直线运动的位移随时间变化规律的图像。(如图1)2.图像判读3.图像应用(1)可求出任意时刻物体的位置和任意位置对应的时刻。(2)可求出通过某一位移所用的时间和某一时间段物体通过的位移。(3)可判断物体运动性质:图像为直线表示物体
First, the displacement - time image (s-t image) 1 image meaning of the vertical axis displacement, abercrombie and fitch, the horizontal axis represents the time to make a reflection of the linear motion of the object displacement with time variation of the image. (Figure 1) 2. Image interpretation 3. Image applications (1) can be obtained at any time the position of the object and any position corresponding time. (2) The displacement of an object passing through a certain time and a certain period of time can be obtained. (3) can determine the nature of the object movement: the image is a straight line that object
