Teksty: They Might Be Giants. Here Comes Science (Amazon.com Exclusive) [CD/DVD]. Speed and Velocity.

When I'm on an airplane
And we're on a runway
Ready to take off
And then we're in the air

Motion, direction, acceleration
Motion, direction, acceleration

I've got speed
That's how fast I am moving
I've got velocity
That's my speed and direction

When I'm on my Big Wheel
Skateboard, roller coaster
Race car, motorcycle
Rocket ship into outer space

Motion
(Keep movin', keep movin', keep movin')
Direction
(Which way, anyway, uptown, all around)

Acceleration
(Let's go faster)
Acceleration
(Let's go faster)

I've got speed
(That's how fast I am moving)
I've got velocity
(That's my speed and direction)

I've got speed
(That's how fast I am moving)
I've got velocity
(That's my speed and direction)
