Speed, distance and time

The slope on a distance-time graph represents the speed of an object.

The velocity of an object is the speed in a particular direction, so the slope on a velocity-time graph represents the acceleration of an object. The distance travelled is equal to the area under the velocity-time graph.

**speed (m/per second) = distance travelled (m) time take (seconds)**

Remember to use the speed, distance and time triangle to help rearrange the equation. Distance at the top, with speed and time underneath, so **distance = speed x time**

Distance-time graphs

The vertical axis on a distance time graph is the distance travelled from the…
