Drag spheres, rockets, and planets onto a canvas. Apply gravity, Coulomb forces, springs, and more. Watch real physics equations come to life — instantly, in your browser.
PHYSIX is a complete drag-and-drop physics simulator built for students, teachers, and curious minds. No downloads, no sign-ups, no code.
Spheres, boxes, rockets, planets, black holes — drag them onto the canvas and they obey real physics immediately.
Gravity, Coulomb, Lorentz, spring, drag, thermal, nuclear — layer as many forces as you need on any body.
Position, velocity, energy, angular momentum — visualised in real time on live graph panels with formula overlays.
Simulate a Coulomb orbit at the nanometre scale or a full solar system spanning billions of kilometres.
25+ presets map directly to BINAS, IB, GCSE, and AP physics curricula — load a preset and start teaching immediately.
Slow time to 0.001× to study collisions frame-by-frame, or fast-forward 100× to watch orbital decay over centuries.
Load a preset in seconds, project it on a whiteboard, and demonstrate Newton's laws, orbital mechanics, or EM fields without any setup. Every simulation links to a real formula.
Experiment with initial conditions, change masses and forces, and see exactly how the equations change in real time. Build intuition for concepts that feel abstract on paper.
Prototype orbital mechanics, test collision models, or validate spring-mass assumptions before writing a single line of code. Export data via the live graph panel.
What happens if you put a black hole next to a neutron star? What does a double pendulum's chaos look like? PHYSIX lets you answer questions like these in under a minute.
PHYSIX runs entirely in your browser. There is no install, no subscription, no account. Open the simulator and start building physics experiments in under 10 seconds.
