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.
Can uniform angular velocity has acceleration?
No, uniform angular velocity implies that an object is moving in a circle at a constant rate. Since acceleration is defined as any change in velocity (either speed or direction), if the angular velocity is constant, there is no acceleration present.
With which constant velocity the disk rotates at a constant speed?
The disk rotates at a constant speed when the angular velocity remains constant. This means the disk rotates at a constant angular velocity, maintaining a consistent rate of rotation without speeding up or slowing down.
With constant velocity the disc rotates at a constant speed?
Angular
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.
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 ball's angular velocity A ball at the end of a string of length 0.75 m rotates at a constant speed in a horizontal circle?
A ball at the end of a 0.75 m string rotating at constant speed in a circle has an angular velocity of (2 pi) divided by (time to complete one revolution). Time to complete one revolution = (speed) divided by (2 times pi times radius). If you write this algebraically and then simplify the fraction, you find that the angular velocity is (4 times pi2 times radius) divided by (speed) = (29.609/speed) radians/sec. The speed is expressed in meters/sec. The solution doesn't depend on the orientation of the plane of the circle.
What is the derivative of angular velocity and how is it calculated?
The derivative of angular velocity is angular acceleration. It is calculated by taking the derivative of the angular velocity function with respect to time. Mathematically, angular acceleration () is calculated as the rate of change of angular velocity () over time.
What is constant angular speed?
Constant angular speed means that an object is rotating at a steady rate, moving through equal angles in equal time intervals. This means that the object's angular velocity, or rate of rotation, remains the same over time.
In orbital motion the Angular Momentum of the system is?
In orbital motion, the angular momentum of the system is constant if there is no external torque acting on the system. This is a result of the conservation of angular momentum, where the product of the rotating body's moment of inertia and angular velocity remains constant unless acted upon by an external torque.
How can one determine the angular acceleration when provided with the angular velocity?
To determine the angular acceleration when given the angular velocity, you can use the formula: angular acceleration change in angular velocity / change in time. This formula calculates how quickly the angular velocity is changing over a specific period of time.
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.
