Learn and revise motion in a straight line, acceleration and motion graphs with BBC Bitesize Combined Science AQA Synergy study guide.

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled.

For those of you remaining, I am going to show you another way to find the acceleration from this distance-time data. Let's go back to our kinematic equation (assuming we start with zero velocity).
