Key standards

Visual physical commonsense (V-PC)

  • A stone moves through the air under gravity-driven acceleration and enters the pond.
  • The stone enters the water producing realistic ripples and a splash, and then sinks below the surface.

Audio physical commonsense (A-PC)

  • The splash sound has a sharp water-impact onset followed by a brief watery scatter of droplets.

Cross-modal physical commonsense (AV-PC)

  • The splash sound onset coincides with the visible moment the stone contacts the water surface.
