Building the particle model

Building the particle model

Particle classification diagram showing fundamental particles as quarks and leptons, and hadrons as baryons and mesons with example quark contents

The quark-lepton model sorts matter particles into fundamental particles and hadrons. Quarks and leptons are fundamental, while hadrons are made from quarks.

Step-by-step lessons on Edexcel A Level Physics Quark-lepton model and particle interactions. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
