Willebrord Van Rooijen Snell
• To the tune:”Sweet Betsy From Pike”
• The web address to find the original set of lyrics and mp3 file is http://www.haverford.edu/physics/songs/snell.htm
• Physics lyrics by Marion McKenzie and Walter Smith (Google “Physics Songs”)
• C is a comfortable key
• Image from the Haverford website
C G7 CCome listen and learn, I’ve a story to tell, C Am G G7I sing of the genius of Willebrord Snell C Em F CA mathematician who lived long ago G7 CIn the Netherlands where the Rhine river does flow.
C G7He set for his mind occupations of worth, Am G G7 Improved navigation and measured the Earth! C Em F CHe gave us the sine law, that wonderful guy, G7 CAnd he made more precise calculation of
Verse 1
Chorus
C F (or C) G (or G7) Am (or C)Singin’ n1 sine theta-sub-1, hey, hey, hey, C F (or C) G (or G7) CEquals n2 sine theta-sub-2, hip hooray!
𝑛1𝑠𝑖𝑛θ1=𝑛2𝑠𝑖𝑛θ2
C G7 CHis greatest feat came in Sixteen Twenty-one, Am G G7When optics as science was really begun! C Em F CWhile flashes of lightning illumined his page, G7 CHe wrote down Snell’s law, his great gift to the age!
C G7 CSo if you wear glasses or like to fry ants, Am G G7Be grateful your lenses were not made by chance! C Em F CAstronomers hail him with each new-found star! G7 CMicroscopists toast him from each sleazy bar!
Verse 2
Chorus
C F (or C) G (or G7) Am (or C)Singin’ n1 sine theta-sub-1, hey, hey, hey, C F (or C) G (or G7) CEquals n2 sine theta-sub-2, hip hooray!
𝑛1𝑠𝑖𝑛θ1=𝑛2𝑠𝑖𝑛θ2
C G7 CNow some credit Harriot, others Descartes, Am G G7Both studied refraction, and both were real smart. C Em F CBut we prefer Willebrord van Rooijen Snell G7 CHe laid down the law, and he did it darn well!
Verse 3
Chorus
C F (or C) G (or G7) Am (or C)Singin’ n1 sine theta-sub-1, hey, hey, hey, C F (or C) G (or G7) CEquals n2 sine theta-sub-2, hip hooray!

The Projectile Song• To the tune:”The Old Folks
At Home”• Music and original words by
Stephen Foster• C is a comfortable key• Written to assist NCEA2
learners
When a thing is thrown and it zips offIt will chase a parabolic arc
We can do this with a gun or ballOr even Fido’s stick when in the park
An object that’s not held up by anythingWill plunge to earth like concrete in free-
fallAs well as that, in a horizontal senseThere is no force that pushes it at all
Projectiles – Verse 1
Chorus – your turnHorizontally, its speed
is setOf acceleration that
way, it is freeVertically, everything
that’s not held upAccelerates to earth,
with value “g”
Projectiles are objects that are in the airFree from almost all external force
We ignore all lift & thrust & drag but weMust include the vector, weight, of
course
To find the range of anything that’s thrown about
We need to find the time until it landsThe vertical velocity, when t is nought
Combined with “g” will put it in our hands
Projectiles – Verse 2
Chorus – your turnHorizontally, its speed
is setOf acceleration that
way, it is freeVertically, everything
that’s not held upAccelerates to earth,
with value “g”
Finally, now we know our time of flight
And the constant horizontal speed
We can find the distance ‘til the object drops
And thus we then have all the stuff we need
Projectiles – Verse 5
Chorus – last timeHorizontally, its speed
is setOf acceleration that
way, it is freeVertically, everything
that’s not held upAccelerates to earth,
with value “g”
The Nuclear Physics Song
• To the tune:”Baby Blue”• Music and original words by George Baker• G is a comfortable key to sing it in
• The purposes of the song are to:
• Help students understand why energy is released in nuclear reactions (AS 3.5-90522)
• Explain why BOTH fission and fusion release energy
• Show that c2 is the link between mass and energy.
Henri Becquerel looked in his drawer
And what he saw there he’d not seen before
Uranium fogged the photo paper although it was wrapped
From where did this energy come?
In total a remarkable sum
The potential was enormous if only this resource could be tapped
Nuclear Physics V1
Chorus – your turnNucleus, the nucleus
Elusive source of high energy
Extremely small, almost no volume at all
And Rutherford gave it an I.D.
The amount of energy did amaze
Alpha, Beta and Gamma rays
And nobody knew just what it was that powered the Sun
“Mass and energy” (said Einstein)
“Are equivalent”; their values entwine
C2 is the ratio; 90 thousand trillion to one
Nuclear Physics V2
Chorus – your turnNucleus, the nucleus
Elusive source of high energy
Extremely small, almost no volume at all
And Rutherford gave it an I.D.
Fission is an energy source
Fusion powers stars, and our Sun, of course
The puzzle is, they’re opposites yet both of them can generate heat
The secret at the very heart
Is the “mass per nucleon” U-shaped chart
Coming in from each end will drop “m” and give off “E” – now that’s neat
Nuclear Physics V3
Chorus – last timeNucleus, the nucleus
Elusive source of high energy
Extremely small, almost no volume at all
And Rutherford gave it an I.D.
The Simple Harmonic Motion Song
• To the tune:”Swing Low, Sweet Chariot”
• (F is a comfortable key to sing it in)
S.H.M.– chorus demoSimple Harmonic Motion
Harmonic motion, simple to see
Simple Harmonic MotionOne on T gives
frequency
SHM– verse 1A bouncing swingbridge; a korimako sings
Harmonic motion, simple to seeA natural frequency seen for all things
One on T gives frequency
All has mass and springinessHarmonic motion, simple to see
If you have more k then the period’s lessOne on T gives frequency
S.H.M.– chorus
Simple Harmonic MotionHarmonic motion,
simple to seeSimple Harmonic Motion
One on T gives frequency
SHM– verse 3S.H.M. – an energised state
Harmonic motion, simple to seeThe energy cycles too; with twice the rate
One on T gives frequency
Energy shows exponential decayHarmonic motion, simple to see
Subcritical damping makes it that wayOne on T gives frequency
S.H.M.– chorusSimple Harmonic Motion
Harmonic motion, simple to see
Simple Harmonic MotionOne on T gives
frequency
SHM– verse 5S.H.M. can be diagnosed
Harmonic motion, simple to see“a” proportional to “y” but the signs are
opposedOne on T gives frequency
The field of applications; wide and bigHarmonic motion, simple to see
So get your head around the waves from trig.One on T gives frequency
S.H.M.– chorus (last time)
Simple Harmonic MotionHarmonic motion,

One on T gives frequency
The Capacitor Song
• To the tune:”Mockingbird Hill”
• Music and original words by Vaughn Horton
• F is a comfortable key
Chorus - DemoFaraday is the chappie whose name we all say
Well almost, we leave off the suffix bit, “ay”
Capacitance is measured in Coulombs per Volt
But Farads is easier; a better result
Chorus – Your turnFaraday is the chappie whose name we all say
Well almost, we leave off the suffix bit, “ay”
Capacitance is measured in Coulombs per Volt
But Farads is easier; a better result
If you take some electrons from a metal sheetAnd give them to its partner, symmetrical, neatThen you’ll separate charge and store energyThe capacitance will be E nought, A upon d
(oA/d)
Capacitors act as electrical springsTheir stored energy can do handy thingsLike saving your data when the battery’s
impairedThe energy stored is a half C V squared
(E=1/2CV2)
Verse 1
ChorusFaraday is the chappie whose name we all say
Well almost, we leave off the suffix bit, “ay”
Capacitance is measured in Coulombs per Volt
But Farads is easier; a better result
Verse 2And in AC circuits the voltage flip flops
(and) Therefore the current through the cap barely stops
This flip flopping current has power to impressA nice, smoothed out value is IRMS
But the currents that flow, VC will retardTheir ratio is measured in Ohms, that’s not hard
But the Ohms do not measure resistance you seeAs the energy’s returned, it’s reactance, XC
ChorusFaraday is the chappie whose name we all say
Well almost, we leave off the suffix bit, “ay”
Capacitance is measured in Coulombs per Volt
But Farads is easier; a better result
Verse 3If the frequency rises, reactance then
dropsThere’s more current flowing, less time for
the stopsThe same will occur if C’s value does rise
Less reactance again, that can’t be a surprise
If you lift f or C, the reactance will dropNothing else affects it, just those two, full
stop.Two pi times their product, viz 2fC
Then find the reciprocal;voila, XC
ChorusFaraday is the chappie whose name we all say
Well almost, we leave off the suffix bit, “ay”
Capacitance is measured in Coulombs per Volt
But Farads is easier; a better result
The Snell’s Law Song (and Dance)
• The tune, dance moves and web link all are secret until after completion!
• Physics Words by Anonymous of Haverford College in the USA
• Only one verse so it’s easy to learn• F is a comfortable key
Snell’s LawSnell’s Law, n times the
sine of the thetaIf the n gets lower then
the theta will get greaterIf the n be greater then the light will get there
laterHey, n sine theta!
The Snell’s Law Song (and Dance)
• The tune and dance moves are from the Macarena by Los Del Rio
• The web link to the file is http://www.haverford.edu/physics/songs/macsnell.htm
• A database of Physics Songs exists at http://www.haverford.edu/physics-astro/songs/
