相遇是直线运动中的常见问题,可以用图象直观表示相遇.表示两质点相遇的图象主要有位移图象和速度图象.1位移图象解读相遇图象解读位移-时间图象(x-t图象)的斜率表示速度,在同一位移图象中画出的两个质点的位移图象交点表示两质点相遇.由同一坐标系中两个质点的位移图象可以直接得到两质点的最大距离和相遇时刻.
Encounter is a common problem in linear motion, you can use the visual representation of the encounter that the two particles meet the main image of displacement and velocity images .1 displacement image interpretation encounter image interpretation displacement - time image (xt Image) of the slope of the speed that the two images in the same displacement image of the displacement of the image intersection point that two particles meet by the same coordinate system, two particle displacement images can be directly obtained the maximum distance of two particles And meet the moment.
