63Mathematical descriptions of physical laws — For worded descriptions and criteria of physical laws, see Physical law. For the nomenclature used see Physical quantity and Defining equation (physics). Physical laws are often summarized by a single equation, or at least a small set of… …
64Bohr model — In atomic physics, the Bohr model created by Niels Bohr depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus mdash;similar in structure to the solar system, but with… …
65Velocity — In physics, velocity is defined as the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second: (m/s) or ms 1. The scalar… …
66Thermodynamic temperature — is the absolute measure of temperature and is one of the principal parameters of thermodynamics. Thermodynamic temperature is an “absolute” scale because it is the measure of the fundamental property underlying temperature: its null or zero point …
67Orbit — This article is about orbits in celestial mechanics, due to gravity. For other uses, see Orbit (disambiguation). A satellite orbiting the Earth has a tangential velocity and an inward acceleration …
68ARPES — Angle resolved photoemission spectroscopy (ARPES) , also known as ARUPS angle resolved ultraviolet photoemission spectroscopy , is a direct experimental technique to observe the distribution of the electrons, or more precisely, the density of… …
69Gravitational two-body problem — The gravitational two body problem concerns the motion of two point particles that interact only with each other, due to gravity. This means that influences from any third body are neglected. For approximate results that is often suitable. It… …
