Material Physics Benchmark: Fragility and Rigidity
A comparative physics benchmark template designed to systematically evaluate material-specific behavior under identical impact conditions. This three-scenario scaffold tests whether the model maintains accurate physical properties for glass (fragile/shattering), metal (rigid/elastic collision), and fabric (compliant/deformation). Critical for validating physics-native understanding of material properties in video generation.
Stages
A glass sphere (clear, smooth, reflective) positioned on a white marble surface in a neutral environment. Soft studio lighting with subtle shadows. A metal ball (solid steel, 50 grams) falls from exactly 1 meter height at velocity 5 m/s, striking the glass sphere at a 45-degree angle. The impact causes the glass sphere to shatter into realistic fragments — radial crack patterns emanating from impact point, fragments falling with gravitational consistency, light refracting through shards. The marble surface shows a fine dust layer from impact.Establish material physics baseline for fragile material. The model must understand glass as a brittle, failure-mode material.
A metal sphere (solid steel, 200 grams) positioned on the same marble surface under identical lighting and environmental conditions. The identical steel ball (50g) falls from the same 1 meter height at 5 m/s, striking at 45 degrees. The steel sphere deforms elastically under impact — slight compression visible on contact surface, rapid rebound, kinetic energy transferring to motion rather than material failure. The surface shows no fragmentation, only localized deformation. Both spheres retain structural integrity.Test elastic material behavior: the model must differentiate between fragile shattering (glass) and elastic collision (metal).
A fabric sphere (cotton weave, off-white color, 150 grams) on the same marble surface. The steel ball falls from 1 meter at 5 m/s, striking at 45 degrees. The fabric sphere absorbs energy through compliant deformation — visible compression, temporary indentation at impact point, followed by slow recovery as elastic fibers restore shape. No shattering, no rigid bounce, but gradual energy dissipation. Surface fibers may show slight disturbance or dust, but structural continuity preserved.Test compliant material physics: the model must understand fabric as an energy-absorbing material with intermediate rigidity between glass and metal.
