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} ...

Acceleration (a)- the rate of change of an object’s velocity over time. Displacement ... need to find out the solution. The first equation can be derived using a velocity-time graph for a ...

The speed is \( \frac {20}{10} = 2~m/s\). Key fact The gradient of a distance-time graph represents speed. When displaying a journey, the vertical axis will often represent the distance from a ...
