The full Cambridge International AS & A Level Physics course: every AS Level topic from measurement to particle physics, and every A Level topic from circular motion and fields to quantum, nuclear, medical physics and cosmology, explained in plain language.
Lesson 1 is free to try. The other 140 lessons in Physics and its exam practice are for schools on RudimentaryLabs.
How physicists describe, measure and estimate quantities, handle uncertainty and work with vectors.
Describing straight-line and projectile motion with graphs and the equations of uniform acceleration.
Newton's laws, momentum and how resistive forces shape real motion.
Turning effects, equilibrium, and the pressure and upthrust produced by fluids.
Work done by forces, conservation of energy, efficiency, power and mechanical energy stores.
How materials stretch, squash and store energy, from springs to the Young modulus.
Progressive waves, how they carry energy, the Doppler effect, the electromagnetic spectrum and polarisation.
What happens when waves meet: stationary waves, diffraction, interference and the diffraction grating.
Charge, current, potential difference, power, resistance and resistivity.
Circuit diagrams, e.m.f. and internal resistance, Kirchhoff's laws and potential dividers.
The nuclear atom, radioactive emissions, antiparticles, quarks and leptons.
Angular measures, centripetal acceleration and the forces that keep things moving in circles.
Newton's law of gravitation, field strength, potential and orbits.
Thermal equilibrium, temperature scales and the energy needed to heat and change state.
The mole, the ideal gas equation and the kinetic theory linking molecules to pressure and temperature.
Internal energy, work done by gases and the first law of thermodynamics.
Simple harmonic motion, its energy, damping and resonance.
Electric field strength, Coulomb's law, potential and the motion of charges in fields.
Storing charge and energy in capacitors and how they discharge through a resistor.
Magnetic forces on currents and moving charges, fields from currents and electromagnetic induction.
Describing sinusoidal a.c., r.m.s. values, rectification and smoothing.
Photons, the photoelectric effect, wave–particle duality and atomic energy levels.
Mass–energy equivalence, binding energy, fission and fusion, and the mathematics of radioactive decay.
How ultrasound, X-rays, CT and PET scanning let doctors see inside the body.
Measuring stars and galaxies with light, and the evidence for an expanding Universe.
