Reference: OCR
A graph on which the slope gives acceleration: a horizontal line means constant velocity, a rising line means acceleration and a falling line means deceleration, while the area under the line gives the distance travelled.
A graph on which the vertical axis is velocity and the horizontal is time, so the gradient is a change in velocity divided by a time.
