Position velocity accel-er-ation
They are in order like a one, two, three
Velo-ci-ty is changing your position
Acceleration changes your velo-ci-ty

Let's start with a stop! Your velocity is zero
position's just a measure of where you are
And if you never give it an acceleration
You're gonna stay parked in your little car
But if you change to positive acceleration
It adds to your velocity and off you go
Velocity gets added to your old position
It's speed in a direction, watch the numbers grow
(Position! It's where you are! Velocity! It's speed in a direction!
Acceleration! Any change in your velocity!)

(chorus)

Now if I were to coast at acceleration zero
I'd still be rollin' my velocity
I won't be speeding up or slowing down
Cause zero means I'm rolling friction-free!
Now if I want to slow it down I have to give it
Acceleration with a little minus sign
So adding to velocity will make it smaller
Slowing down my progress on that number line
(Position! It's where you are! Velocity! It's speed in a direction!
Acceleration! Any change in your velocity!)

(chorus)

Now you might wonder if your car was turning
Could that be acceleration, too?
Velocity is speed in a direction
So your hypothesis is clearly true!
Any change to speed or direction
has to have a force to make it go
That force is the mass times acceleration
I know 'cause Isaac Newton told me so!
(Position! It's where you are! Velocity! It's speed in a direction!
Acceleration! Any change in your velocity!)

(chorus)
