Forces · Physics labs for class 9–12
Physics you can drag, slide and measure
Eleven interactive labs and animated explainers that run real physics live. Change a value, watch the graph respond, then test yourself with a quiz. Free, no sign-up.
Interactive labs
Pick a topic. Every lab has live readouts, guided lessons and a link to related quiz questions.
Mechanics
Projectile motion, free fall, pendulum and collisions, with live v–t and s–t graphs.
Work, power & energy
Work at an angle, the work–energy theorem on a slope, the loop-the-loop and the power of a car.
Newton's laws & friction
Force and motion, static and kinetic friction, inclines, connected bodies and lifts.
Refraction & prisms
Snell's law, total internal reflection, prisms and dispersion, optical fibres and lens-maker's formula.
Circuit builder
Build series and parallel circuits with up to 15 parts and watch the current flow.
Optics
Mirrors, lenses and ray diagrams with a draggable object and focal point.
Waves & sound
Standing waves, two-source interference and the Doppler effect.
Rotational motion
Torque and balance, a rolling-shapes race, and angular momentum.
Thermodynamics
A gas box with real measured pressure, plus PV diagrams for four processes.
Electricity & magnetism
Field lines, electromagnetic induction and a live R-L-C phasor diagram.
Logic gates
Wire AND, OR, NOT and more into circuits, then check the output step by step.
Modern physics
Animated explainers: Bohr model, photoelectric effect and semiconductor bands.
Learn, practise and explore
Lessons to read, questions to test yourself, and games to make it stick.
