momentum

a big ball with a big velocity

has more oomph

than a small ball with big velocity

or a big ball with small velocity

easy, peasy, butter squeezy

velocity in a ball - big or small

times the essence of its core -

its rest mass, to be sure

tells the oomph of the motion

momentum it is for your information

now, wouldn't we all be spooked 

if appears a rare fruit

in our backyard or the hood

just out of the blue

so, no to spooky stuff, in real we are good

the momentum's source

is always a force

which can often be measured

by the change observed

before and after the serve

denying all the spooky crud

saves us from serious dud

and once we have done that thing

we don't need no more thinking

for us the momentum is logically conserved
