Hooke and Newton
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:
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.
