A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
A common example of quantum numbers is the possible state of an electron in a central potential: (,,,), which corresponds to the eigenstate of observables (in terms of ), (magnitude of angular momentum), (angular momentum in -direction), and .
velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian heat capacity ratio: unitless surface tension: newton per meter (N/m) delta: change in a variable (e.g. ) unitless Laplace operator: per square meter (m −2)

The word physics comes from the Latin physica ('study of nature'), which itself is a borrowing of the Greek φυσική (phusikḗ 'natural science'), a term derived from φύσις (phúsis 'origin, nature, property'). [6] [7] [8]
They include common physical phenomena, physical quantities and physics equations (and formula, relations) as well as some general concepts in physics. The main article for this category is Outline of physics § General concepts of physics .
In contrast, the authoritative glossary attached to the textbook on Biological Nomenclature produced by the Systematics Association displays a very dismissive attitude to the question; for example, the only relevant entries it presents on the subject of the term sensu are: sens. str.: see s.s. sens. lat.: see s.l. sensu amplo: see s.l.
Transmission of information by changing the magnitude of a carrier signal, for example sending sound by radio. analog circuit A circuit where currents and voltages vary continually within some practical range, in proportion to some signal. analog filter An analog circuit that alters some frequency-related property of a signal. analog signal ...
