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]

"Good Honey Tastes Sweet":

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

"Virgins Are Rare":

Volts = Amps x Resistance[1]

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]

• Roman Men Invented Very Unusual X-Ray Guns [5]
• Ronald McDonald Invented Very Unusual & eXcellent Gherkins.[6]

• Remember My Instructions Visible Under X-Ray Glasses

• Raging Martians Invaded Venus Using X-ray Guns.

• Rahul's Mother Is Visiting Uncle Xavier's Garden.

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.

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

To remember the Mohs hardness of minerals;

Tall Gene Calls Florence At Our Quarters To Correct Dumbness.[9]

To remember the decay chain of ²³⁸U, commonly called the "radium series" (sometimes "uranium series"). Beginning with naturally occurring uranium-238;

${\displaystyle {\begin{array}{l}{}\\{\ce {^{238}_{92}U->[\alpha ][4.468\times 10^{9}\ {\ce {y}}]{^{234}_{90}Th}->[\beta ^{-}][24.1\ {\ce {d}}]{^{234\!m}_{91}Pa}}}{\begin{Bmatrix}{\ce {->[0.16\%][1.17\ {\ce {min}}]{^{234}_{91}Pa}->[\beta ^{-}][6.7\ {\ce {h}}]}}\\{\ce {->[99.84\%\ \beta ^{-}][1.17\ {\ce {min}}]}}\end{Bmatrix}}{\ce {^{234}_{92}U->[\alpha ][2.445\times 10^{5}\ {\ce {y}}]{^{230}_{90}Th}->[\alpha ][7.7\times 10^{4}\ {\ce {y}}]{^{226}_{88}Ra}->[\alpha ][1600\ {\ce {y}}]{^{222}_{86}Rn}}}\\{\ce {^{222}_{86}Rn->[\alpha ][3.8235\ {\ce {d}}]{^{218}_{84}Po}->[\alpha ][3.05\ {\ce {min}}]{^{214}_{82}Pb}->[\beta ^{-}][26.8\ {\ce {min}}]{^{214}_{83}Bi}->[\beta ^{-}][19.9\ {\ce {min}}]{^{214}_{84}Po}->[\alpha ][164.3\ \mu {\ce {s}}]{^{210}_{82}Pb}->[\beta ^{-}][22.26\ {\ce {y}}]{^{210}_{83}Bi}->[\beta ^{-}][5,013\ {\ce {d}}]{^{210}_{84}Po}->[\alpha ][138.38\ {\ce {d}}]{^{206}_{82}Pb}}}\end{array}}}$
