[net.space] Derivatives of position

KFL%MIT-MC@sri-unix.UUCP (01/28/84)

From:  Keith F. Lynch <KFL @ MIT-MC>

  The way I have always heard it was:

				Position	0th derivative
Rate of change of Position:	Velocity	1st derivative
Rate of change of Velocity:	Acceleration	2nd derivative
Rate of change of Acceleration:	Jerk		3rd derivative
Rate of change of Jerk:		Thump		4th derivative
Rate of change of Thump:	?		5th derivative

  Does anyone know what the 5th, etc, derivatives of position are
called?

The fifth and higher time-derivatives of position are called "noise".

This is all wrong, it really should be:

Rate of change of Position:    Velocity
Rate of change of Velocity:    Acceleration
Rate of change of Acceleration:Jerk

but, the 5th derivative is called inauguration (change of the Jerk)!!
