In engineering, derivitives over time are ubiquitous. Accelleration due to gravity? Second time-base derivative of position.

And "jerk" can only be used to describe certain people we may run into.

LOL. So, the derivatives beyond rate of change of acceleration?
After “jerk” comes “snap” then “crackle” then “pop”.
