Jerk: Rate of Change of Acceleration

    Just learned something new today from a discussion on Biomech-l.

    The proper term for the time derivative of acceleration is "jerk".

    The order of derivation of position is as follows:

    1st derivative: velocity

    2nd derivative: acceleration

    3rd derivative: jerk

    4th derivative: snap

    5th derivative: crackle

    6th derivative: pop


    Here is the discussion:

    And did you know

    Momentum equals mass times velcoity!
    Force equals mass times acceleration!
    Yanks equals mass times jerk!
    Tug equals mass times snap!
    Snatch equals mass times crackle!
    Shake equals mass times pop!


    or so they say

    Just a quick correction, thrid derivative should read

    Yank equals mass times jerk
