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).

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.
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.
When the rotational speed of a rotating system doubles its angular momentum?
Gets doubled
What is an angular velocity?
An angular velocity is the angle turned in a given time by a body rotating around an axis.
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
A remote control car's wheel accelerates at 22.4 rad-sec squared If the wheel begins with an angular speed of 10.8 rad-sec what is the wheel's angular speed after exactly 3 turns?
A measure of how fast a rotating body is changing its angular position. The average angular speed (w) is obtained by dividing the http://www.answers.com/topic/angular-distance-2 through which the body rotates by the time taken: w = θ/t, where θ = angular distance, and t = time taken in seconds.
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
What is the approximate angular speed of a wheel rotating at the rate of 5.0 rev per second?
The exact angular speed is 5*360 = 1800 degrees per second. The appoximate speed could be 2000 dps
If a body is rotating is it necessarily being acted upon by an external torque?
No. Torque is required only for producing angular acceleration. A body rotates with constant angular velocity if no external torque acts on it.
What is the angular speed in radians per second of a wheel that is rotating at o 18 rpm?
18 revolutions = 113.097 radians.
How is rpm related to speed?
More rpm means more speed, but the speed is also related to the diameter of the rotating object. The exact formula is: speed = angular speed x radius (assuming compatible units are used: for example, speed in meters/second, angular speed in expressed in radians/second, radius in meters).
