For what it's worth, some higher derivatives have (somewhat whimsical)
names. The derivative of acceleration with respect to time is called
jerk, the derivative of jerk is called snap or jounce, the derivative
of snap is crackle, the derivative of crackle is pop. Someone was a
breakfast cereal fan. The highest derivative I know of that's actually
used is snap, when designing the transition of roads or railroads from
straight to a curve they try to minimize the 'snap' of a vehicle
following the transition segment.

I'd heard of jerk.  Many years ago, Norman Dean "invented" the Dean
drive, a system of rotating masses with the center of rotation of the
masses being moved at particular times in the rotation cycle.  He showed
that the weight of the assembly was decreased when running - on a
bathroom scales.

my friend, heard?? It's enough to push body on a line with a forcemeter on
it. You get the slope for the jerk since the acceleration is not constant.
Ohh my, heard of. And you want to speed higher than light, do you. Are we
from amrica??

What you get is that scales, measure deflection, in the system,
while balances, measure not deflection, according to references.
Physics is an open and closed system.
