A Level Physics
- 9702 A Level Ch.16 · Lesson 16.1Circular motion: horizontal, vertical and conicalAnalyse any circular motion with ω, v = rω and F = mv²/r: strings, bends, banked tracks, vertical circles, conical pendulums.
- 9702 A Level Ch.17 · Lesson 17.1Gravitational fieldsUse F = GMm/r², g = GM/r² and φ = −GM/r, and analyse circular orbits, including geostationary satellites.
- 9702 A Level Ch.22 · Lesson 22.1Coulomb’s law and electric fieldsUse F = Qq/4πε₀r², E = Q/4πε₀r² and V = Q/4πε₀r for point charges, combine fields and potentials, and compare with gravity.
