2. Angular Motion and the Equations of Angular Motion
Angular displacement, velocity and acceleration measured in radians, and the rotational equivalent of the suvat equations.
3. Torque, Moment of Inertia and Rotational Dynamics
Moment of inertia as rotational mass, torque as the rotational equivalent of force, and rotational kinetic energy.
4. Angular Momentum and Its Conservation
Angular momentum as the rotational equivalent of momentum, and how its conservation explains spinning objects that speed up or slow down.
5. Gravitation and Orbital Mechanics
Newton's law of gravitation, gravitational field strength, and using Kepler's third law to relate orbital period and orbital radius.
6. Stellar Physics: Luminosity and Classification
Using Wien's law and the Stefan-Boltzmann law to relate a star's temperature, radius and luminosity, and how stars are classified.
7. General Relativity and Cosmology
The equivalence principle underlying general relativity, its main observational evidence, and an introduction to modern cosmology.
7. Wave-Particle Duality and the de Broglie Wavelength
The evidence that matter, not only light, shows both wave-like and particle-like behaviour, and calculating the de Broglie wavelength.
8. The Bohr Model and Atomic Energy Levels
The Bohr model's quantised electron orbits, and calculating photon energies from transitions between hydrogen's energy levels.
9. Evidence for Quantum Theory and the Uncertainty Principle
Black-body radiation as further evidence for quantum theory, and the Heisenberg uncertainty principle's fundamental limit.
13. Interference, Diffraction and Diffraction Gratings
Two-source interference revisited in more depth, and calculating diffraction grating angles and the highest order a grating can produce.
14. Polarisation and Refraction in Depth
Polarisation as evidence light is a transverse wave, and calculating Brewster's angle, the incidence angle for fully polarised reflection.
12. Electric Fields and Coulomb's Law
Calculating the electrostatic force between point charges with Coulomb's law, and the electric field and potential energy that follow from it.
13. Magnetic Fields and Forces on Conductors
Calculating the force on a current-carrying conductor and on a moving charge in a magnetic field, and circular motion in a field.
14. Electromagnetic Induction and Faraday's Law
Magnetic flux, Faraday's law of induction, Lenz's law for the induced EMF's direction, and calculating motional EMF.
15. Capacitors and Inductors in Circuits
The RC time constant governing how quickly a capacitor charges and discharges, and self-inductance's equivalent behaviour for inductors.
16. AC Circuit Analysis: Reactance and Impedance
Calculating capacitive and inductive reactance, combining them with resistance into impedance, and resonance in an LC circuit.
