P2-1 : Motion

Speed and Velocity

The table below shows the distances travelled by a car over a given amount of time:

Distance (m) 0 1000 2000 3000 4000 5000 6000

Time (s) 0 40 80 120 160 200 240

We can represent this as a graph:

We call this type of graph a distance-time graph as it plots distance travelled against time

taken. A slope on a distance-time graph represents speed. The steeper the slope is, the

greater the speed. We can use chosen figures to calculate the speed from the graph

This formula can be rearranged to show either of the following formulae which we use to

work out distance or time:

Generally, speed is measured in metres per second (m/s).
