A small electric motor spins slowly, producing a low uneven hum. A switch is flipped to high speed, and the sound jumps to a smooth higher-pitched whir.

Key standards

Visual physical commonsense (V-PC)

  • A switch is visibly flipped at some point in the clip, and after the flip the electric motor visibly speeds up its rotation.
  • The motor is a recognizable electric motor with a rotor or shaft that spins while the surrounding housing stays still.

Audio physical commonsense (A-PC)

  • The motor's whir shifts to a noticeably higher pitch after the switch is flipped.
  • The sound has the characteristic electric-motor whir or friction timbre.

Cross-modal physical commonsense (AV-PC)

  • The shift to a higher-pitched whir aligns in time with the visible switch flip and the motor speed-up.
  • The higher-pitched whir corresponds to the high-speed state after the switch flip.
  • The lower hum corresponds to the slow initial state before the switch flip.
