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.

Key fact The gradient of a distance-time graph represents speed ... 2 \frac{2}{3}\) miles per hour. Note: We must use the total change in distance and the total change in time.

They are afraid to embrace the power of the graph ... velocity. So really, the only way you could do this is with a zero initial velocity. However, if you use other methods to collect position ...
