Angular and momentum
Angular momentum is conserved in a system where there is no net external torque, and its conservation helps explain many diverse phenomena.
Angular momentum in quantum mechanics differs in many profound respects from angular momentum in classical mechanics.

Angular displacement of a body is the angle in radians ( degrees, revolutions ) through which a point or line has been rotated in a specified sense about a specified axis.
* Angular frequency of a wave, in fluid dynamics ( angular frequency is usually represented by but this may be confused with vorticity in a fluid dynamics context ).
Angular frequency omega | ω ( in radians per second ), is larger than frequency nu ( letter ) | ν ( in cycles per second, also called Hertz | Hz ), by a factor of 2π.
Angular displacement of the cantilever results in one photodiode collecting more light than the other photodiode, producing an output signal ( the difference between the photodiode signals normalized by their sum ) which is proportional to the deflection of the cantilever.
Constant Angular Acceleration is very similar to Constant Linear Velocity, save for the fact that CAA varies the angular rotation of the disc in controlled steps instead of gradually slowing down in a steady linear pace as a CLV disc is read.
Angular field of view is typically specified in degrees, while linear field of view is a ratio of lengths.
Angular and concept
Angular velocity is not the time rate of change of orientation, because there is no such concept as an orientation vector that can be differentiated to obtain the angular velocity.
Angular and motion
* CAV ( Constant Angular Velocity ) or Standard Play discs supported several unique features such as freeze frame, variable slow motion and reverse.
Angular momentum is a property of a physical system that is a constant of motion ( also referred to as a conserved property, time-independent and well-defined ) in two situations:
Angular and about
* Angular displacement, a change in orientation of a rigid body, the amount of rotation about a fixed axis
* Angular resolution: about 4 arcminutes, or approximately 0. 07 °, which corresponds to 1. 2 m at a 1 km distance.
Angular velocity is a vector quantity that describes the angular speed at which the orientation of the rigid body is changing and the instantaneous axis about which it is rotating ( the existence of this instantaneous axis is guaranteed by the Euler's rotation theorem ).
Angular and point
* Angular magnification — For optical instruments with an eyepiece, the linear dimension of the image seen in the eyepiece ( virtual image in infinite distance ) cannot be given, thus size means the angle subtended by the object at the focal point ( angular size ).
