derivatives wrt time

it's all about the change baby

and the rate of change with time

know the changing property

differentiate and show with a prime

call that its derivative

it ain't that sublime

a thing moves

from a to b

it may have done so

circuitously

but displacement be the shortest measure 

from where it was to where it is

not much room for creativity

the first derivative is velocity

which on further differentiation

(why don't we call it derived ?

but that's just an aside)

gives acceleration

moving to the order third

we get what's called jerk

also known as jolt

and 'tis the reason

when the bus stops

gotta grab hold

fourth is jounce

or snap as with sticks

then comes crackle

and pop at six

seventh is lock 

in the lingo of physics

there's one more that i know of

the eighth is called drop

and that is where they stop

it may seem a lot

but all and more is experienced

simply driving around the block.
