This is a categorized list of physics mnemonics.
Mechanics
Work: formula "Lots of Work makes me Mad!": Work = Mad: M=Mass a=acceleration d=distance
Thermodynamics
Ideal gas law "Pure Virgins Never Really Tire": PV=nRT 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.
Gibbs's free energy formula "Good Honey Tastes Sweet": (delta)G = H - T(delta)S. 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.
Electrodynamics
Ohm's law "Virgins Are Rare": Volts = Amps x Resistance
Relation between Resistance and Resistivity REPLAY Resistance = ρ (Length/Area)
Inductive and Capacitive circuits 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.
Open and Short circuits "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
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 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.
Electromagnetic spectrum In the order of increasing frequency or decreasing wavelength of electromagnetic waves;
