A ping-pong ball bounces on a wooden table with sharp ticks. Then drops onto carpet, and the bounces become soft and nearly silent.

Key standards

Visual physical commonsense (V-PC)

  • A ping-pong-ball-sized ball bounces plausibly on the wooden table with higher rebounds and bounces on the carpet with lower rebounds.

Audio physical commonsense (A-PC)

  • The table bounces have sharp bright ticks and the carpet bounces are distinctly softer and nearly silent.

Cross-modal physical commonsense (AV-PC)

  • Each bounce sound coincides in time with a visible ball contact on its corresponding surface.
  • The sharp bright ticks correspond to the ball bouncing on the wooden table.
  • The soft, nearly silent bounces correspond to the ball landing on the carpet.
