The constant maximum speed reached by a falling object when the resistance of the medium through which it is falling prevents further acceleration.

  1. Maximum falling speedB2formal

    The constant maximum speed reached by a falling object when the resistance of the medium (like air) prevents further acceleration.

    zh终端速度

    • A skydiver reaches terminal velocity after falling for about 12 seconds.
    • The terminal velocity of a raindrop is much lower than that of a human.
    • Engineers calculate terminal velocity to design safe parachutes.
