Interactive labs · simulate, predict, solve
Fly the model before you trust it.
Each lab pairs a live simulation bench with the practice engine: predict the outcome first, watch the physics contradict or confirm you, then solve randomized numeric problems whose wrong answers are matched against the known wrong paths — so feedback names the mistake, not just the miss.
Projectile motion
One clock, two axes that never talk to each other.
Fly the two-axis model until the independence is obvious, then prove it on fall time, range, peak height, and air time.
- Bench
- live trajectory + component vectors
- Practice
- 6 types · randomized values
Collisions & momentum
Two ledgers, one impact — only one survives.
Watch the Σp and ΣKE meters through sticky and elastic impacts, then choose the right conservation law under pressure.
- Bench
- two-cart track + conservation meters
- Practice
- 6 types · randomized values
Circuits
Same parts, four times the power.
Watch current actually flow through series and parallel wirings, then apply the right sharing rule under pressure.
- Bench
- live circuit + animated current
- Practice
- 4 types · randomized values
More benches follow the same recipe — one trap family, one live model, one practice desk. Next candidates: rotation (ROT-06 rolling) and springs/SHM (SHM-03).
next Know which lab you need
The diagnostic tells you which trap family costs you the most points — and therefore which bench to fly first.
