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

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