The conservation rule
The conservation rule
Momentum is the product of mass and velocity: p=mvp = mvp=mv. It is a vector quantity, so direction matters, and its SI unit is kg m/s\text{kg m/s}kg m/s.
Step-by-step lessons on AQA GCSE Physics 5.7.2 Conservation of momentum. Each one builds up to exam-style questions. Build a strong grip on equations, units and Key Stage 3 fundamentals before tackling the more demanding topics like electromagnetism, the particle model of matter and space physics.
