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 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.

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.
