51angular aperture — n the angle subtended at the principal focus of an optical system (as a microscope) by the diameter of its entrance for light …
52angular artery — n the terminal part of the facial artery that passes up alongside the nose to the inner angle of the orbit * * * arteria angularis …
53angular vein — n a vein that comprises the first part of the facial vein and runs obliquely down at the side of the upper part of the nose * * * vena angularis …
54Angular momentum — For a generally accessible and less technical introduction to the topic, see Introduction to angular momentum. Classical mechanics Newton s Second Law …
55Angular momentum coupling — Coupling in science Classical coupling Rotational–vibrational coupling Quantum coupling Quantum mechanical coupling Rovibrational coupling Vibronic coupling Rovibronic coupling Angular momentum coupling …
56Angular velocity — Do not confuse with angular frequency The unit for angular velocity is rad/s.In physics, the angular velocity is a vector quantity (more precisely, a pseudovector) which specifies the angular speed, and axis about which an object is rotating. The …
57Angular diameter — The angular diameter or apparent size of an object as seen from a given position is the “visual diameter” of the object measured as an angle. In the vision sciences it is called the visual angle. The visual diameter is the diameter of the… …
58Angular frequency — Not to be confused with angular velocity. Angular frequency ω (in radians per second), is larger than frequency ν (in cycles per second, also called Hz), by a factor of 2π …
59Angular momentum operator — In quantum mechanics, the angular momentum operator is an operator analogous to classical angular momentum. The angular momentum operator plays a central role in the theory of atomic physics and other quantum problems involving rotational… …
60angular momentum — Physics. the product of the moment of inertia of a body about an axis and its angular velocity with respect to the same axis. Also called moment of momentum. [1865 70] * * * Property that describes the rotary inertia of a system in motion about… …
