Most of us were handed physics as equations to memorise. Kinetica hands it back as something you can feel: a spinning disc paints light as it travels, and the way it moves is the lesson. Bounce it off walls, slingshot it around a sun, bend it through glass — and the ideas behind the picture quietly explain themselves.
These are the real game, running embedded. The left is Level 1 with spin switched off; the right adds spin and the whole picture changes.
A still ball bounces off a wall like light off a mirror — the angle going in equals the angle coming out. Give that ball a spin, and the tidy rule quietly breaks. At the instant it touches the wall, the disc's phase — how far around its spin it happens to be — nudges the rebound one way or the other.
You never see the spin directly. Yet it is the secret engine of every path Kinetica paints: turn spin off and the trails are calm and mirror-neat; turn it up and they weave into something alive and unrepeatable. That single, felt twist is the doorway — and once you are through it, gravity and light are waiting in the next two worlds.
The disc rolls a frictionless table and rebounds by its spin phase, painting light between bounces. This is mechanics you can watch.
A sun sits in the middle and pulls. Now the disc curves — loop it into an orbit, or slingshot it around the sun to reach a target it could never reach in a straight line.
A slab of glass crosses the arena. The disc behaves like a ray of light — its path kinks as it enters, and at a shallow enough angle it can't escape at all.
Honest status: the Table is fully verified, so its demo runs live above. The Field and Lab engines are built and playable inside the game, but their standalone embedded demos are held back until the orbital and refraction constants are tuned by eye — we won't showcase physics we haven't checked.
Around twenty-nine ideas are already felt inside the engine — never as a wall of text, but the moment the disc does the thing. Each tag below is marked 🟢 real simulation (the engine truly computes it) or 🟡 maths of the picture (a pattern in what you see), because honesty about which is which is the whole point.
~29 felt now, on the way to a planned catalogue of 36. We don't claim a concept until the engine actually simulates it.
Free sandbox. Set the spin, the speed, the shape, and just watch it paint. Concepts whisper softly as they happen.
Place a target and try to hit it — across all three worlds. In the Field that means a slingshot; in the Lab, bending light through glass.
Play, then pause the moment something surprises you and a card explains it with the live numbers from your own run.
Every concept opens into its own standalone article — a live demo, the principle, how it shows up in the game, real-world examples, a glossary, an FAQ, and a 32-question set to test yourself. All thirty are below, grouped by world.
A self-contained, play-to-learn physics exhibit. You spin a disc that paints glowing trails, and across three worlds you feel mechanics, gravity and optics rather than just reading about them.
No. Every idea is explained in plain twelve-year-old language, on the spot, tied to exactly what you just saw the disc do. Play first; learn as curiosity strikes.
The Table is kinetic billiards — a spinning disc whose spin decides each bounce. The Field adds a sun whose gravity bends the path into orbits and slingshots. The Lab adds glass that refracts the disc like a ray of light.
Because the disc's phase — how far around its rotation it has turned at the instant of contact — sets the rebound. With no spin it is a plain mirror bounce; with spin, the phase quietly steers it.
Around twenty-nine are already felt inside the engine across the three worlds, on the way to a planned catalogue of thirty-six. We don't claim a concept until the engine truly simulates it.
Yes — Kinetica is a single page. Open it and play, with nothing to install.
Kinetica follows a feel-first method: you play, and the instant something surprises you, a layered card explains it — a one-line whisper in play, a study card, or a full standalone article with a live demo, glossary, FAQ and a 32-question set. Every concept is tagged 🟢 real simulation (the engine truly computes it) or 🟡 maths of the picture (a pattern in what you see), because honesty about which is which is the whole point.
