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.

Check definition, SI unit and formula for acceleration. Here we have also provided some questions and numerical problems based on acceleration.

Consider two discrete times t 1 and t 2 on these traces shown in freeze-frames of the motion below. At t 1, the angular velocity is zero, with a non-zero (negative) angular acceleration. At that time, ...
