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 ...

The area under a speed-time graph represents the distance travelled. The object is accelerating at \(\frac{8}{4} = 2~m/s^2\). It travels \(\frac{1}{2} \times 4 \times 8 = 16~m\). Between 4 and 7 ...
