![A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters.
It can be adapted to similar equations e.g. F = ma, v = fl, E = mcDT, V = pr h and t = rF sinth. When a variable with an exponent or in a function is covered, the corresponding inverse is applied to the remainder, i.e.
r
=
V
p
h
{\displaystyle r={\sqrt {\frac {V}{\pi h}}}}
and
th
=
arcsin

t

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:
And then they all lived happily ever after. [3]
"There are zeroCOVS grazing in the field!"
This is a mnemonic to remember the useful fact that:
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"
Additionally, the fictitious name Roy G. Biv can be used as well.
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;
| Radio waves, Microwaves, Infrared, Visible light, Ultraviolet, X-Rays, Gamma Rays |
In the order of increasing wavelength;
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 = alpha decay
B = beta decay
