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

Learn the difference between distance, displacement, speed and velocity, and how to calculate distance, speed and acceleration.

Why do you always make a graph in physics lab? It's not just for fun, there is a reason. Here is an example.

The difference is that the velocity-time graph reveals the speed of an object—and whether it’s slowing down or accelerating—while the position-time graph describes the motion of an object ...
