Music from the PBS program Dragon Tales
Words by Walter Fox Smith and Marian McKenzie
Additional words by me
CHORUS:
Hooke on the left, Newton on the right
Gives you an equation that’s really out of sight.
Short and sweet, full of hidden delight
And the spring goes up and down and down, and the spring goes up and down.
Up at the top, the motion flip-flops
Velocity goes plus to minus smoothly, as it ought.
Speed’s greatest when the force is naught
And the spring goes up and down and down, and the spring goes up and down.
Increase the mass to slow the spring down
A weaker spring will take more time to turn the mass around.
From m and k the period’s found
And the spring goes up and down and down, and the spring goes up and down.
Potential and kinetic cycle back and forth, you see.
But their sum is just as constant as a constant can be.
Hooke and Newton were rivals in their day
But partners for eternity is how they’re going to stay.
Minus kx is equal to ma
And the spring goes up and down and down, and the spring goes up and down.
(CHORUS 2×)
(repeat last line)
