Because angular speed is some number of revolutions or angle rotated each second. It has units of s-1 (per second) and is therefore a frequency.

Define angular speed?
In physics, angular frequency ω (also referred to by the terms angular speed, radial frequency, circular frequency, orbital frequency, radian frequency, and pulsatance) is a scalar measure of rotation rate. Angular frequency (or angular speed) is the magnitude of the vector quantity angular velocity. The term angular frequency vector is sometimes used as a synonym for the vector quantity angular velocity.[1]One revolution is equal to 2π radians, hence[1][2]whereω is the angular frequency or angular speed (measured in radians per second), T is the period (measured in seconds), f is the ordinary frequency (measured in hertz) (sometimes symbolised with ν),
What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
What is an angular frequency?
An angular frequency is a scalar measure of rate of rotation.
Is angular speed the same as angular acceleration?
No. Acceleration and speed are related in the same way irrespective of being linear or angular. Acceleration is rate of change of speed.
A wave with frequency 10.2Hz and amplitude 42.2 mm moves in the positive x direction with a speed of 4.3 ms What is the waves angular frequency?
If the angular frequency is really what you want to know, then you don't need the amplitudeor speed. All you need is the frequency, and the angular frequency is just that times [ 2 pi ].w ('omega', or angular frequency) = 10.2 x 2 pi = 64.0885 radians per second (rounded)Sometimes this is hard to understand or explain. But it's clear if we use degrees instead of radians ...If your 10.2 Hz means that you have a wheel turning 10.2 times a second, then how many degreesdoes it turn in a second ?Well, there are 360 degrees in one whole turn, so 10.2 turns is (360 x 10.2) = 3,672 degrees per second.That's all there is to it. That's the 'angular' velocity. But it's normally done in radians instead of degrees,and there are [ 2 pi ] radians in one whole turn.

Is angular speed a vector?
Scalar. Angular frequency vector is roughly synonymous with angular velocity.
What is the meaning of angular frequency for a body undergoing simple harmonic motion?
Angular frequency differs from frequency by factor '2Pie'. It has the dimension of reciprocal time(same as angular speed). Its unit is radian/sec. Or you can simply say that angular frequency is the magnitude of angular velocity(a vector quantity).
What is the angular speed of a body vibrating at 50 circus per second?
Angular speed = (2 pi) x (frequency) = 314.16 per second (rounded)
What is the Relation between angular velocity and frequency?
If there is a rotation, "angular velocity" and "angular frequency" is the same thing. However, "angular frequency" can also refer to situations where there is no rotation.
How do you define angular frequency?
Angular frequency is related to linear frequency as w = 2 x pi x f wher w = angular frequency linear frequency is cycles per second, or number of oscillations per second, called Hertz angular frequency for f = 1 = 2 pi f = 2 pi, or one revolution. It has units of radians per second
Does Simple harmonic motion have always constant angular frequency?
Yes. There are certainly other kinds of motion, whose angular frequency is not constant, but those are not called "simple harmonic" motion.
Question about linear speed and angular speed?
what is the relation angular speed and angular speed with clutch disc plate
What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
How is the speed of an AC motor that's being driven by a constantly changing sine wave voltage effected?
Assuming the sine wave's angular frequency is what's changing, the motor will speed up and slow down in proportion to that frequency.
When the angular speed of an object increase its angular momentum may or may not increase?
if the angular speed of an object increase its angular momentum will also increase
What is an angular frequency?
An angular frequency is a scalar measure of rate of rotation.
