Is the average speed equal to the magnitude of the average velocity?

  • Physics - ,

    Only if all velocities that are averaged are in the same direction.
    That is usually not the case.

    The mean velocity of all the molecules in a gas is zero (unless the container is moving or the gas is flowing) but the average speed of the molecules is quite high -- comparable to the speed of sound.
