potential and kinetic energy

 of all the energies that there be

them all be just two kind -

potential and kinetic

as the words say to an average mind

potential be the capability

while kinetic, in motion you find.

all movement is energy

be it the electrons on the grind

responding to an electric field

or a magnet, if you wind

the moving electron sea

to a core well inclined

them electrons get the wire heating

buzzing faster with time

the most inaudible sound but be

moving particles in the medium's bind

and the light and others of the creed

just be the photons cruising in line 

nothing to say of other things moving

solid, liquid, gas or an idea sublime

them all be kinetic energy

ain't too hard on the mind

to talk of the potential energy 

a simple way it be defined

it's just an object's capability

to cause motion when thus destined -

could be from the right company

a privileged spot where enshrined

or some stress internal may be

charge etc as predefined

them nuclear particles that we see

weigh more individually than combined

potential energy is that exactly

a boom a bang when freed from the bind

them chemicals in them batteries

when over-charged may burst the confines

all the same with gravitational field

fallen oranges stain their rind

same for springs and elasticity

shouldn't forget to remind

learning such, a question creeps

how is the difference assigned ?

well, let me tell this simple trick

that us mortals have designed

we assign the potential negative

and everything gets well aligned.
