Don’t just learnthe answer.Change the world.

Turn any mechanics question or textbook diagram into a living 3D experiment. Predict it. Run it. Prove it.

CREATE AN EXPERIMENT

What do you want to understand?

Ask anything in mechanics — falling objects, projectiles, pendulums, springs, collisions, orbits. The AI builds each world live.

02 · START WITH A PROVEN PARADOX

Three worlds. One way of thinking.

Every lab begins with a prediction, because seeing an answer is not the same as changing your mind.

03 · THE MECHANISM

Predict. Run. Prove.

No answer is ever handed to you. You earn it by testing the world, then breaking it on purpose.

STEP 01

Commit a prediction

Lock in what you think happens before anything moves. That friction is where a wrong intuition finally gets exposed.

STEP 02

Run the real world

A deterministic 3D physics engine plays it out. Motion, measurements, and evidence charts stay perfectly in sync.

STEP 03

Explain, then transfer

Say why it happened, get rubric feedback, then change one variable and predict again in a world that shifted.

04 · YOUR TURN

Ask a question. Change the world. Prove it.

One question becomes a world you can rerun. The physics is deterministic, so what you learn is real.
