What momentum measures
Momentum measures how hard it is to stop or change the motion of an object. It depends on both mass and velocity, so a heavy fast object has a large momentum.
Step-by-step lessons on AQA A Level Physics Momentum. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
