Angular frequency
rate of change of the phase angle / From Wikipedia, the free encyclopedia
In physics, angular frequency, ω, (also called the angular speed, radial frequency, and radian frequency) is a measure of rotation rate. A high rate of angular frequency means something is turning very fast. The angular frequency is the magnitude of the vector quantity angular velocity which is also known as angular frequency vector .
It is useful in many areas of maths and science as it allows understanding of many properties of physical objects in our world. In SI units, angular frequency is measured in radians per second, with dimensions t−1 since radians are dimensionless.
