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]
where
ω 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.
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.
Does angular speed depend on distance?
when something moves with constant angular speed (w), as in a rotating disk, the speed (v) as you move away from the center depends on distance (r), but the angular speed does not. Mathematically, v = wr.
What are the practical applications of Angular Speed Angular Displacement Angular Velocity and Angular Momentum?
These are used in lots of engineering problems related to rotation.
Why angular speed is called angular frequency?
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.
What is an angular speed of a rotating body?
Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).
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.
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
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.
Is angular speed a vector?
Scalar. Angular frequency vector is roughly synonymous with angular velocity.
Does angular speed depend on distance?
when something moves with constant angular speed (w), as in a rotating disk, the speed (v) as you move away from the center depends on distance (r), but the angular speed does not. Mathematically, v = wr.
What is the angular speed of a windmill with 40 feet and speed of 80 revolutions per minute?
The angular speed is 480 degrees per second.
What are the practical applications of Angular Speed Angular Displacement Angular Velocity and Angular Momentum?
These are used in lots of engineering problems related to rotation.
How do you convert linear speed to angular speed?
To convert linear speed to angular speed, divide the linear speed by the radius of the rotating object. The formula for this relationship is: angular speed (ω) = linear speed (v) / radius (r). This will give you the angular speed in radians per second.
How do you convert angular speed to linear speed?
divide the linear speed by the radius
Why angular speed is called angular frequency?
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.
