- Physical quantities, kinematics and dynamics SI base units, homogeneity of equations, estimates, scalars and vectors (resolving and adding), systematic and random errors, precision and accuracy, combining uncertainties (add absolute uncertainties for sums; add fractional uncertainties for products and quotients).
- Forces, energy, deformation of solids Moments, couples and torque; equilibrium conditions; centre of gravity; upthrust (Archimedes' principle); drag and viscous forces.
- Waves and superposition Transverse and longitudinal waves; displacement, amplitude, phase difference, period, frequency, wavelength, speed (v = fλ); intensity ∝ amplitude² and I = P/A; the Doppler effect for sound: f₀ = fₛv/(v ± vₛ).
- Electricity and DC circuits I = ΔQ/Δt; Q = ne; I = nAvq; V = W/Q; R = V/I; P = VI = I²R = V²/R; resistivity R = ρL/A; I–V characteristics of resistors, filament lamps, diodes, thermistors and LDRs.
- Thermal physics and ideal gases Thermal equilibrium; thermodynamic (kelvin) scale; internal energy as the sum of random kinetic and potential energies of molecules; first law of thermodynamics ΔU = q + W.
