Assuming you mean "Constant angular velocity", let's break it down.
Constant, meaning "something that does not or cannot change or vary".
Velocity is distance over time, or "speed". Angular velocity is the angular distance (such as "one rotation")
An example of velocity would be 60 Miles per Hour (MPH). That would be that in one hour, an object would travel 60 miles.
An example of angular velocity would be 45 Degrees per Hour.
For a real world example, Earth turns 1 full revolution every day. "1 revolution per day" is an angular velocity. Lets convert this to a different unit. There are 360 degrees in 1 revolution. Therefor, we can say that Earth has an angular velocity of 360 degrees per day." We can convert this unit again. There are 24 hours in one day. 360 divided by 24 = 15 degrees per hour, which is another example of angular velocity.
Simply put, angular velocity is the speed at which something is rotating.
In computers, angular velocity is commonly used to describe a mechanical hard disk drive. Hard drive speeds are measured in Rotations per Minute (RPM) and are commonly 4200, 5200 or 7200 RPM. The faster the speed of the hard drive, the faster it can read and write data.

Define constant angular velocity and explain how it is applies to a CD?
Angular velocity is the measure of angular displacement (in one or the opposite) direction over a unit period of time. In the context of CDs , one unit in which this can be measured is the number of revolutions per second. A constant angular velocity means that the CD is turning through the same angle each second.
With constant velocity the disc rotates at a constant speed?
Angular
When does centripetal force double?
Since a=Rω², when you double the radius, but hold the angular velocity constant, you double the force. Also when you increase the angular velocity or velocity by a factor of √2 and hold the radius constant.
What moment of inertia does not depend on angular velocity?
An object that is rotating at constant angular velocity will remain rotating unless it is acted upon by an external torque.
Which of the clock arm rotates are constat speed or constant velocity?
Ignoring the fact that some clocks "jump", for example once a second, each of the three arms moves at constant angular velocity. The speed, in this case, is constant; the velocity is not since the direction changes. On the other hand, sometimes people use a vector to describe an angular velocity. Angular momentums add nicely with vector representation.
How do you find out the direction of angular accelaration?
The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down.The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing downThe direction of the angular acceleration will be negative if the angular velocity is clockwise and the object's rotation is speeding up or if the angular velocity is counterclockwise and the object's rotation is slowing downThe angular acceleration will not have a direction if the object's angular velocity is constant
A rotating fan blade has kinetic energy when rotating with constant angular velocity when the angular velocity is reduced to one third what will happen to the kinetic energy?
It will decrease by a factor 9.
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).
What is the difference between angular velocity and angular momentum?
angular momentum and angular velocity
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
Relation between linear velocity and angular velocity?
linear velocity= radius* angular velocity
How does constant angular velocity apply to CD standards?
If a stationary base reference line and a zero line on the disk both extend from the outer edge of the disk to the center of rotation, constant angular velocity will ensure the periodic angle changes between the two lines remains a constant. This allows the CD to be played smoothly.
