Subject: Re: Third derivative

I'm not sure if it is a formal or informal name, but we always called the
third derivative of position the "jerk".  The reason it seems so appropriate
is because if the third derivative is zero (acceleration is constant) then
you can not tell the difference between a 1g gravity pull from a mass and a
1g accelerated movement (this is the classic idea of Einstein's closed
elevator illustration). It is the change of acceleration that causes you to
feel a "jerk".

Hope that is what the real physics pros call it...
good luck.
