or \(= {ms}^{-2}\). A negative gradient shows the rate of 'slowing down' or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient.

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 ...

Because the length of each segment is the distance travelled in one second, the heights of the bars form a bar graph of velocity vs. time. During each second the graph shows that the velocity ...
