9702 · AS & A Level · Paper 4
A2-level definitions and formulae — same drill system, A2 content. Work through until every card is clean.
Cambridge A Level Physics 9702 Paper 4 (A Level Structured Questions) tests A2-only material alongside some revisited AS content. Definitions form a reliable source of marks: “define gravitational field strength”, “explain what is meant by simple harmonic motion”, “define the becquerel”, and “state what is meant by the photoelectric effect” appear regularly. The mark scheme is precise: “force on a mass” is insufficient for gravitational field strength (it must be “force per unit mass on a small test mass”); omitting the proportionality condition from the SHM definition loses the mark.
This deck covers 108 recall items from the A2 component of the 9702 specification (2025–2027), organised by topic: Motion in a Circle (angular velocity, centripetal acceleration, centripetal force); Gravitational Fields (gravitational field strength, Newton’s law of gravitation, gravitational potential, orbital velocity, escape velocity); Oscillations (SHM definition and conditions, angular frequency, period, energy relationships, damping types); Thermal Physics (internal energy, first law of thermodynamics, specific heat capacity, ideal gas laws, kinetic theory); Capacitance (definition, energy stored, time constant); Magnetic Fields (magnetic flux density, tesla, force on current, Hall effect, Faraday’s and Lenz’s laws); Alternating Currents (r.m.s. values, rectification, smoothing); Quantum Physics (photon energy, photoelectric effect, de Broglie wavelength, energy levels, line spectra); and Nuclear Physics (binding energy, mass defect, nuclear radius, fission, fusion, decay constant, half-life, activity).
Use alongside the Paper 2 (AS) flashcard deck to cover the full 9702 definition list, and the uncertainties trainer for practical paper preparation.
No spam, no daily nudges. Just a note when Paper 4, Paper 6, or the 9702 trainers are ready — plus the occasional examiner tip the week before an exam window.
