List of physics mnemonics

This is a categorized list of physics mnemonics.

"Lots of Work makes me Mad!":

Work = Mad:

M=Mass

a=acceleration

d=distance^[1]

"Pure Virgins Never Really Tire":

PV=nRT^[1]

The equation PV = nRT represents the ideal gas law, where P is the pressure of the gas, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature.

"Good Honey Tastes Sweet":

(delta)G = H - T(delta)S.^[2]

Gibbs free energy is a thermodynamic state function that measures the energy available for a system to do work, and is given by the formula G = H – TS, where H is enthalpy, T is temperature, and S is entropy.

"Virgins Are Rare":

Volts = Amps x Resistance^[1]

REPLAY

Resistance = ρ (Length/Area)

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]

"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

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).

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]

In the order of increasing frequency or decreasing wavelength of electromagnetic waves;

• 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
• Retention of Migrant & Immigrant data Varies Under eXternal GDPR

In the order of increasing wavelength;

• Good Xylophones Use Very Interesting Musical Rhythms.^[7]
• Godzilla-X Using Violence In Meeting Room.
• Granddad Xavier Unfortunately Vomitted In My Room.
• Grandma's X-Large Underwear Visible In My Room.

Microwave frequency bands ordered by increasing wavelengths (decreasing frequencies): King Xerxes Can Seduce Lovely (princesses)^[8]

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
