{change~in~time} = \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 ...

Oh, that’s right – make a graph. I don’t know why we always make a graph but it’s not a real physics lab ... measure the distance traveled (Δx) along with the time it takes to travel ...

Distance-time graphs show distance on the vertical axis and time on the horizontal axis. The gradient of a distance-time graph represents speed because gradient = \( \frac{\text{change in y}}{\ ...
