Free notes for all thirteen Cambridge IGCSE Physics topics, with Core and Supplement clearly marked, plus a quick quiz, topical questions with mark schemes, and original Paper 2, 4 and 6-style practice sets.
Syllabus 0625
Every topic is a free notes page. Core is studied by all candidates; Supplement is examined on the Extended papers only.
Content overview 1
Measuring, moving, stretching, turning, falling — and the energy maths behind it all.
18 Core · 10 Supplement · 16 min read
How to measure length, volume and time accurately, how to read distance–time and speed–time graphs, what links weight to mass through gravitational field strength, and how to find the density of anything — including awkward irregular shapes.
15 Core · 6 Supplement · 17 min read
What a resultant force does to an object, how springs stretch until they stop obeying the rule, why a seesaw balances, and how to find the point an object wobbles about — its centre of gravity.
0 Core · 4 Supplement · 13 min read
Mass in motion: how momentum p = mv is conserved in every collision, why following distance beats a stiff bumper, and how the same ideas explain recoil, rocketry and crash safety.
9 Core · 7 Supplement · 17 min read
Where energy is stored, how it moves between stores, what work and power really measure, and how the world’s power stations, turbines and solar panels turn raw energy into electricity — with efficiency counting every joule.
3 Core · 1 Supplement · 11 min read
Why sharp knives cut and wide tyres grip soft ground, and why deep water pushes harder on a dam than shallow water — the force-per-area idea that runs through engineering and diving.
Content overview 2
Particles and heat, then wave behaviour from ripples to sound, light and the electromagnetic spectrum.
24 Core · 20 Supplement · 21 min read
Everything hot and cold, explained with particles: why solids keep their shape, what absolute zero really means, why the sea warms slowly, and how conduction, convection and radiation move thermal energy around your home.
17 Core · 5 Supplement · 17 min read
What every wave has in common — crests, troughs, wavelength and speed — how ripples bend and spread, and why your voice cannot cross a vacuum but ultrasound can map a seabed.
15 Core · 9 Supplement · 18 min read
How light bounces off mirrors, bends entering glass, hides behind critical angles inside optical fibres, and splits into a rainbow — plus the ray diagrams for converging and diverging lenses that examiners love.
5 Core · 5 Supplement · 12 min read
One family of waves at one cosmic speed limit — radio to gamma — that carries your calls, cooks your dinner, sterilises hospital kit and lets doctors see inside you, plus the price of too much exposure.
Content overview 3
Circuits and electromagnetism, the unstable nucleus, and the Earth’s place in the Universe.
35 Core · 16 Supplement · 20 min read
Charge on the move: what current really is, why ammeters sit in series while voltmeters sit in parallel, how series and parallel circuits split voltage and share current, and what stops the mains from hurting you.
22 Core · 14 Supplement · 18 min read
From fridge magnets to power stations: fields around magnets and wires, how motion generates electricity, how electricity makes motion and sound, and how transformers shift voltage up and down the grid.
18 Core · 13 Supplement · 17 min read
Inside the atom: the tiny massive nucleus, the three emissions it can throw out, how equations keep count of protons and neutrons, how half-life sets the countdown, and how to handle it all safely.
15 Core · 15 Supplement · 16 min read
Our place in it all: why day follows night and summer follows spring, how gravity choreographs planets and comets, how stars are born and die, and what the stretched light of distant galaxies tells us about the beginning of everything.
