frac{change~in~metres}{change~in~seconds} \) = m/s. The gradient of a distance-time graph represents speed. When displaying a journey, the vertical axis will often represent the distance from a ...

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 ...
