Key standards
Visual physical commonsense (V-PC)
- A glass sphere visibly drops and bounces multiple times on a hard surface with continuous physically plausible rigid-body motion and decreasing bounce heights.
- The sphere remains visibly intact transparent glass throughout the clip, without shattering, cracking, or deforming into rubber.
Audio physical commonsense (A-PC)
- Each bounce sound is an elastic rubber boing with the springy resilient timbre of a rubber ball rather than the brittle clink of glass.
Cross-modal physical commonsense (AV-PC)
- Each boing sound onset aligns in time with a visible bounce contact between the glass sphere and the surface.
