Eight labs, three explainers — all live
Eight interactive sandboxes — mechanics through logic gates — plus animated modern-physics explainers on the Bohr model, the photoelectric effect and semiconductor bands — all free, all live.
Mechanics playground
Projectile motion, free fall, collisions, pendulum/SHM — sliders for mass, angle, velocity and gravity, trail rendering, and live v-t / s-t graphs.
liveCircuit builder
Build your own series or parallel circuit with up to 15 resistors, bulbs and capacitors, set the battery's internal resistance, and watch the current actually flow.
liveOptics lab
Ray diagrams for mirrors and lenses, a draggable object and focal point, and live image formation — class 10 light + class 12 ray optics.
liveWaves & sound lab
Standing waves on a string, two-source interference with a draggable detector, and the Doppler effect — three animated sandboxes, live now.
liveRotational motion sandbox
Torque and balance, a rolling-shapes race, and a spinning disk that conserves angular momentum — three animated sandboxes, live now.
liveThermodynamics visualizer
A kinetic-theory gas box with real measured pressure, and a PV-diagram piston sandbox for all four classic processes.
liveElectricity & magnetism lab
Draggable charges with traced field lines, a moving magnet inducing EMF, and a live R-L-C phasor diagram — three animated sandboxes, live now.
liveAtomic & nuclear explainers
Bohr model orbits, the photoelectric effect, and semiconductor band diagrams — animated diagrams, not a sandbox.
liveLogic gate lab
Wire up to 10 AND/OR/NOT/NAND/NOR/XOR/XNOR gates together and press Check answer for a slow, fully-explained reveal of how the signal flows to the output.
