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

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

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 ...
