Velocity–time graph split into two shapes

Illustrative motion: velocity is 5 metres per second from zero to 3 seconds, then decreases steadily to zero at 7 seconds. The displacement is a rectangle plus a triangle.

If the figure is wider than its frame, scroll across to read all labels.

One object moves right at constant velocity, then slows steadily to rest. The dots mark the same four instants in both views; the shaded area under the velocity–time graph equals the 25 m it travels.
