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)
