The AQA A-level Physics Paper 2 (November 2020) explores advanced topics including thermodynamics, gravitation, mass spectrometry, and electromagnetic fields. Key areas involve specific heat capacity, orbital mechanics, escape velocity, electric and magnetic forces, and nuclear decay. Questions test understanding of energy transfer, ideal gas laws, capacitors, and the interactions of subatomic particles. Numerical problems emphasize calculations of time constants, potential energy, and decay rates. Practical applications in nuclear reactors, oscilloscopes, and RC circuits are included. Keywords: AQA Physics, thermodynamics, orbital mechanics, mass spectrometry, capacitors, nuclear physics, electromagnetic fields, ideal gases.
