Apple-Pi
A 100-case evaluation subset (50 simulation + 50 realworld) drawn from a larger 400-case physics benchmark for evaluating physics reasoning in image and video generation models.

Per-case contents
Simulation (sim_subset/<task>/<case_id>/) — generated with NVIDIA Isaac Sim (rigid-body PhysX simulator):

Tasks
Simulation (9 tasks): at_rest, circular, freefall, inclined_plane, inelastic_collision, perfectly_elastic_collision, perfectly_inelastic_collision, projectile, uniform_linear.
Realworld (7 categories): NewtonsFirstLaw/AtRest, Gravity/{Freefall, Projectile}, ConservationofMomentum/{InelasticCollision, PerfectlyElasticCollision, PerfectlyInelasticCollision}, Composition.
Intended use
Zero-shot evaluation of physics reasoning in image- and video-generation models (perception, comprehension, generation tracks). Not intended for training.
