Some aspects of linear motion are more easily seen on velocity-time graphs than on position-time graphs, and some are more visible on position-time graph than on velocity-time graphs. Therefore, it is ...

Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. The object may change direction, eg from forward to backwards, up or down, left or right.

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.
