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? ...Keith

From: Doug Gwyn (VLD/VMB) <gwyn@brl-vld> The fifth and higher time-derivatives of position are called "noise".

From: Alan R. Katz <KATZ@USC-ISIF> 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)!! Alan -------

What do the 5th, etc, derivatives of position mean?!

#R:sri-arpa:-1610100:fortune:8600010:000:403 fortune!rpw3 Feb 5 01:58:00 1984 The third derivative of position with respect to time is also called "jolt" (as well as "jerk"), at least in my college physics class. (I also remember an old sf-novel that spoke of "joltmeters swinging over" at rocket liftoff...)
