It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = πr 2h and τ = rF sinθ. When a variable with an exponent or in a function is covered, the corresponding inverse is applied to the remainder, i.e. and

This is a categorized list of physics mnemonics.
Mechanics
[edit]Work: formula
[edit]"Lots of Work makes me Mad!":
Work = Mad:
M=Mass
a=acceleration
d=distance[1]
Thermodynamics
[edit]Ideal gas law
[edit]"Pure Virgins Never Really Tire":
PV=nRT[1]
Gibbs's free energy formula
[edit]"Good Honey Tastes Sweet":
(delta)G = H - T(delta)S.[2]
Electrodynamics
[edit]Ohm's Law
[edit]"Virgins Are Rare":
Volts = Amps x Resistance[1]
Relation between Resistance and Resistivity
[edit]REPLAY
Resistance = ρ (Length/Area)
Inductive and Capacitive circuits
[edit]Once upon a time, the symbol E (for electromotive force) was used to designate voltages. Then, every student learned the phrase ELI the ICE man as a reminder that:
- For an inductive (L) circuit, the EMF (E) is ahead of the current (I)
- While for a capactive circuit (C), the current (I) is ahead of the EMF (E).
And then they all lived happily ever after.[3]
Open and Short circuits
[edit]"There are zero COVS grazing in the field!"
This is a mnemonic to remember the useful fact that:
- The Current through an Open circuit is always zero
- The Voltage across a Short circuit is always zero
Order of rainbow colors
[edit]ROYGBIV (in reverse VIBGYOR) is commonly used to remember the order of colors in the visible light spectrum, as seen in a rainbow.
Richard of York gave battle in vain"
- (red, orange, yellow, green, blue, indigo, violet).
Additionally, the fictitious name Roy G. Biv can be used as well.
- (red, orange, yellow, green, blue, indigo, violet).
Speed of light
[edit]The phrase "We guarantee certainty, clearly referring to this light mnemonic." represents the speed of light in meters per second through the number of letters in each word: 299,792,458.[4]
Electromagnetic spectrum
[edit]In the order of increasing frequency or decreasing wavelength of electromagnetic waves;
Radio waves, Microwaves, Infrared, Visible light, Ultraviolet, X-Rays, Gamma Rays |
- Road Men Invented Very Unique Xtra Gums [5]
- Ronald McDonald Invented Very Unusual & eXcellent Gherkins.[6]
- Remember My Instructions Visible Under X-Ray Glasses
- Raging (or Red) Martians Invaded Venus Using X-ray Guns.
- Rahul's Mother Is Visiting Uncle Xavier's Garden.
- Ryann May I Visit YoUr eX-Girlfriend?
- Rich Men In Vegas Use eXpensive Gadgets
- Rich Men In Vegas Use X-ray Glasses
- Royal Magicians Interested Viewing Untied X-mas Gifts
In the order of increasing wavelength;
- Good Xylophones Use Very Interesting Musical Rhythms.[7]
- Godzilla-X Using Violence In Meeting Room.
- Granddad Xavier Unfortunately Vomited In My Room.
- Grandma's X-Large Underwear Visible In My Room.
Microwave frequency bands
[edit]Microwave frequency bands ordered by increasing wavelengths (decreasing frequencies): King Xerxes Can Seduce Lovely (princesses)[8]
Other
[edit]Radium series (or uranium series)
[edit]To remember the decay chain of 238U, commonly called the "radium series" (sometimes "uranium series"). Beginning with naturally occurring uranium-238;
A Bitty Bitty Ant Asked Another Ant About Bitty Bitty Ants' Bitty Bitty Aunts
A = alpha decay
B = beta decay
