Skateboard Physics

Can a model land the math behind two dozen skateboard tricks?

What it measures

Signed 3D rotation understanding, projectile-motion arithmetic, landing orientation, and whether a skateboard trick fits its airtime.

Category: physical-reasoning. Status: alpha.

How to run

$ npx benchmark-skateboard list
$ npx benchmark-skateboard run --model <model-id> --provider openrouter
$ npx benchmark-skateboard score results.json

--provider mock runs the whole benchmark offline with no keys. Real models run through OpenRouter (OPENROUTER_API_KEY) or any OpenAI-compatible base URL (OPENAI_BASE_URL, OPENAI_API_KEY).

Data fields

data/tasks.jsonl holds 72 tasks, one JSON object per line (kinds: 72 single).

Human-written skateboard trick glossary

  • Kind: human-written
  • URL: https://github.com/pooriaarab/benchmark-skateboard/blob/main/data/tricks.json
  • Licence: CC0-1.0
  • Retrieved: 2026-10-15T00:00:00.000Z
  • How to get it: Read data/tricks.json; its sources array names each public reference page used to check factual trick combinations.
  • Contamination notes: The glossary and public tasks are visible after 2026-10-15. Final comparisons should generate a private split with a fresh seed and keep it outside the package.
  • Refresh: Review the cited pages yearly or when a factual correction is reported, then record and review any table change.

OpenStax projectile-motion equations

  • Kind: human-written
  • URL: https://openstax.org/books/university-physics-volume-1/pages/4-3-projectile-motion
  • Licence: CC-BY-4.0
  • Retrieved: 2026-10-15T00:00:00.000Z
  • How to get it: Read section 4.3 and docs/methodology.md; only the standard constant-acceleration equations are used.
  • Contamination notes: This is a public method reference, not copied task text. The generated numeric combinations use the benchmark seed.
  • Refresh: Recheck the linked section when the method changes; equations are otherwise stable.

Seeded projectile-motion task generator

  • Kind: synthetic
  • URL: https://github.com/pooriaarab/benchmark-skateboard/blob/main/scripts/gen-tasks.mjs
  • Licence: MIT
  • Retrieved: 2026-10-15T00:00:00.000Z
  • How to get it: Run node scripts/gen-tasks.mjs --seed 20261015 --split public from the repository root.
  • Contamination notes: The 72 public tasks use seed 20261015. For a hidden split, run node scripts/gen-tasks.mjs --seed N --split hidden; .hidden/tasks.jsonl is gitignored and must remain private.
  • Refresh: Generate and review a new public seed for each planned minor data release; do not replace a release in place.

Grader

Strict JSON shape; exact signed rotations in turns; 5% relative tolerance for airtime and peak height; landing and feasibility booleans scored only when both physics values are within tolerance.

Limitations

This dataset contains only the public task split (72 tasks). Hidden evaluation splits use a private seed and are deliberately not part of this dataset. Source kinds: human-written, synthetic. These are evaluation prompts for the benchmark-skateboard benchmark, not training data; scoring requires the package's deterministic grader. See PROVENANCE.md for contamination notes.
