This glossary of physics is a list of definitions of terms and concepts relevant to physics, its sub-disciplines, and related fields, including mechanics, materials science, nuclear physics, particle physics, and thermodynamics. For more inclusive glossaries concerning related fields of science and technology, see Glossary of chemistry terms, Glossary of astronomy, Glossary of areas of mathematics, and Glossary of engineering.

A

Шаблон:TermШаблон:Anchor Шаблон:Ghat {{defn|A scalar measure of rotation rate. It refers to the Шаблон:Gli per unit time (e.g. in rotation) or the rate of change of the phase of a sinusoidal waveform (e.g. in oscillations and waves), or as the rate of change of the argument of the sine function. Angular frequency (or angular speed) is the magnitude of the vector quantity that is Шаблон:Gli. The term angular frequency vector <math>\vec{\omega}</math> is sometimes used as a synonym for the vector quantity angular velocity.

One revolution is equal to 2π radians, hence

<math>\omega = {{2 \pi} \over T} = {2 \pi f} , </math>

where:

ω is the angular frequency or angular speed (measured in radians per second),

T is the period (measured in seconds),

f is the ordinary frequency (measured in hertz) (sometimes symbolised with ν).}}
