The conservation checklist

The conservation checklist

Flowchart showing the order of checks for a particle interaction: charge, baryon number, electron and muon lepton numbers, strangeness, then energy and momentum A particle interaction is allowed only if the totals before and after match. In A Level particle physics, always check charge QQQ, baryon number BBB, electron lepton number LeL_eLe​, muon lepton number LμL_\muLμ​, and remember that total energy and total momentum are conserved too.

Step-by-step lessons on AQA A Level Physics Applications of conservation laws. 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.
