How to judge the difference and relation of VT XT image if the image type is not marked

Vt image, the slope of a straight line is acceleration, the area of the graph is displacement, if the acceleration is a straight line, it is constant acceleration, if it is a curve, it is variable. XT image, the slope of a straight line is velocity, here it is worth saying that the slope is the variable velocity, and the acceleration is constant, and a horizontal line

What does the intersection of physical VT graph mean

It means the speed is the same at this time

In physics, what is the point of intersection in the image of displacement in time

The displacement is the same at that time. To be exact, two objects are in the same position at that time, that is, they meet
