Chapter 1
Quantities and Measurement
Use units, estimates and uncertainty to judge measurements, and represent vector magnitude and direction consistently.
Chapter 2
Forces and Moments
Identify forces, use spring data, calculate turning effects and combine force and moment balances.
Chapter 3
Motion and Forces
Describe signed motion, interpret graphs, derive constant-acceleration equations and connect resultant force with momentum change.
Chapter 4
Energy and Fields
Account for energy, calculate work and power, and connect field direction with force and potential-energy changes.
Chapter 5
Projectile Motion
Use perpendicular motion components, calculate gravitational energy changes and explain a fall with air resistance.
Chapter 6
Collisions
Use signed impulse and momentum accounts, then distinguish elastic, separating inelastic and sticking collisions.
Chapter 7
Circular Motion
Describe uniform turns, explain inward acceleration and identify the real forces supplying the radial resultant.
Chapter 8
Gravitational Fields
Distinguish gravitational force, field strength, potential and potential energy, then use force or energy to analyse an orbit or escape.
Chapter 9
Oscillations
Recognise simple harmonic motion, connect its signed motion graphs and energy, and explain damping and resonance.
Chapter 10
Wave Motion
Distinguish propagation from particle motion, interpret transverse and longitudinal graphs, and calculate wave speed, intensity and polarisation effects.
Chapter 11
Superposition
Combine waves, interpret standing-wave experiments and use interference and diffraction patterns to measure wavelength and judge resolution.
Chapter 12
Temperature and Ideal Gases
Use absolute temperature and particle counts to calculate gas states, derive pressure from collisions and connect temperature to mean particle energy.
Chapter 13
Thermodynamic Systems
Explain internal energy and thermal equilibrium, account for heating and work, and calculate temperature and phase changes with clear system boundaries.
Chapter 14
Electric Fields
Distinguish electric force, field, potential and energy; predict charged-particle motion and account for capacitor charge and stored energy.
Chapter 15
Currents
Connect charge flow and energy transfer, then interpret sinusoidal supplies, equivalent heating and half-wave rectification.
Chapter 16
Circuits
Read and calculate circuits, then connect capacitor constraints and switching paths to exponential behaviour and data.
Chapter 17
Electromagnetic Forces
Calculate current-produced fields and conductor interactions, then analyse field measurements, charged beams and velocity selection.
Chapter 18
Electromagnetic Induction
Use changes in magnetic flux linkage to explain induced e.m.f., its direction and the energy accounts of generators, braking and transformers.
Chapter 19
Quantum Physics
Use photon and matter-wave evidence, probability amplitudes, confinement and atomic energy changes to explain quantum observations.
Chapter 20
Nuclear Physics
Connect nuclear evidence and radiation measurements to decay, conservation, mass defect and energy release.
