# Angular velocity (rotational velocity)

Angular velocity is a measure of the rate of rotation of an object about an axis. It is usually expressed in terms of radians per second.

##### How do you find the rotational angular velocity?

There is no definitive answer to this question as it depends on the specific rotational system in question and the units of measurement that are being used. However, there are a few general methods that can be used to calculate the rotational angular velocity of a system.

One common method is to use the equation:

ω = 2πf

where ω is the rotational angular velocity, f is the frequency of rotation, and 2π is the constant pi. This equation can be used to calculate the rotational angular velocity in terms of rotations per second, or Hertz.

Another common method is to use the equation:

ω = v/r

where ω is the rotational angular velocity, v is the linear velocity of the object, and r is the radius of the object's rotation. This equation is typically used to calculate the rotational angular velocity in terms of radians per second. What is rotational velocity equal to? There is no definitive answer to this question as there is no agreed-upon standard for what rotational velocity should be equal to. However, some common possibilities include angular velocity (measured in radians per second), rotational speed (measured in revolutions per minute), or simply the rate of rotation (measured in degrees per second). Ultimately, it is up to the individual or organization defining the rotational velocity to decide what it should be equal to. Is angular velocity an RPM? No, angular velocity is not an RPM. RPM is a measure of rotational speed, expressed in rotations per minute. Angular velocity is a measure of the rate of change of angular position, expressed in radians per second.

##### What is called angular velocity?

Angular velocity is a measure of the rate at which an object rotates or revolves about an axis. It is usually expressed in terms of radians per second, although it can also be expressed in terms of degrees per second, revolutions per second, or revolutions per minute.

### What is relation between angular velocity and linear velocity?

The angular velocity of an object is the rate of change of its angular position with respect to time. The linear velocity of an object is the rate of change of its linear position with respect to time.

The two concepts are related by the equation:

angular velocity = linear velocity / radius

where radius is the distance from the center of rotation to the object.
