Studio render showing conservation of momentum: BEFORE — 4kg blue trolley moving at 3 m/s hits stationary 2kg red trolley, total momentum 12 kg m/s. AFTER — combined 6kg trolley moves at 2 m/s, momentum still 12 kg m/s. Formula p = mv shown at top.

Figure 1: Conservation of momentum in a collision — total momentum before equals total momentum after

This diagram covers Momentum and Conservation within Momentum for GCSE Physics. Revise Momentum in Forces for GCSE Physics with 15 exam-style questions and 6 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 3 of 12 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
