1. Force & Motion Rap
LYRICS:
Whats up yall, Im figgina show you da notion
Of da reasons why we even have forces and motion
If you dont know da 3 laws, let me splain
His name is sir Issac Newton, hes off da chain!
My man Newton understood da way things move
And these aint theories, they have been proved
Newtons 1st law says objects at rest will stay at rest, not moving, unless
They acted upon by an unbalanced force
And a force is a push or a pull, of course
When forces are balanced, the objects movement doesnt change
The motion is constant, it remains the same
When forces are unbalanced, objects will move
They can fly, fall, jump, dive, wiggle, and groove!
An object in motion will stay in motion
Unless an outside force produces some commotion
They call this 1st law, Inertia. Say what?
Inertia means that things like to say da way dey was.
Whew! Now you know about Newtons 1st law
Now let me thrill you with Newtons 2nd law
In short, force equals mass times acceleration
Memorize this equation, shout it out to da nations!
The larger the object, the more force it needs
It takes more force to lift a plant, than it does to lift the seeds
If you cruisin in a Hummer, you cant stop as fast
Then if you rollin in a Smart Car, cuz yo car got less mass
What? You mean theres physics in my ride?
Newtons laws are all around you, even in da west side!

2. So now we done with da second and we on to #3
Believe me, #3 is about equality
Forces always come in pairs—for every action
There is an equal and opposite reaction
Like when a ball rolls, it stops due to fraction,
I meant friction, not fraction thats a math term!
The world around you has a very strong attraction
Its known as gravity, its never out of fashion
So every pair of forces in my recollection
They always equal and opposite in direction!
So let me see you move like you got some energy
Kinetic energy, potential energy
It is potential when yo body stores da energy
It is kinetic when you choose to use dat energy
There is a synergy between these two energies
They flock together like da biggity birds and da bees
They go together like peanut butter and jelly
The two are homies like Mario and Luigi!
Now you know about Newtons 3 laws
And how his laws are all around yall
Dont forget about da simple machines
Levers and pulleys make yo work a breeze
Next time you sit beneath an apple tree
You can thank my homeboy Newton for his expertise!
