"acceleration" = a = second derivative of position
"jerk" = "jolt" (in UK) = j = third derivative of position
"jounce" = "snap" = s = fourth derivative of position
"crackle" = c = fifth derivative of position
"pop" = p = sixth derivative of position

"momentum" = p
"force" = F = rate of change of "momentum"
"yank" = Y = rate of change of "force"
"tug" = T = rate of change of "yank"

    A dynamical system which passes
through a succession of states, at 
'constant' time intervals, is a clock. 
    Clocks measure times, and can also 
measure the duration of a physical 
process. 
    Cloks can also be used to 'control' 
the evolution of a physical system. 
    If a clock has a good time resolution, 
there is some energy exchange between 
the clock and the physical system whose
evolution is controlled by the clock.
    Both the evolution of the physical 
system and the clock are, thus, perturbed. 
    If  a clock is too precise, the evolution 
of the physical system under control may 
be halted (Zeno effect.)
