The difference between VT representation and ST representation in seventh grade mathematics
VT is an image of how the speed changes with time, and ST is an image of how the distance changes with time. If the VT diagram is horizontal, it means that the speed of the object has been constant, and the ordinate is the speed; If the ST diagram is horizontal, it means that the object is moving in a straight line at a uniform speed, and S divided by T is the speed.
