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.
Angular
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.
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.
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.
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.
The angular momentum is a constant.

To change the speed without changing the angular momentum, you can change the radius of the rotating object. This is because angular momentum is the product of an object's moment of inertia, its mass, and its angular velocity. By adjusting the radius while keeping the other factors constant, you can alter the speed without affecting the angular momentum.
what is the relation angular speed and angular speed with clutch disc plate
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.
If a net torque is applied to an object, it will experience angular acceleration. This is because torque causes rotation and leads to a change in angular velocity. The object's angular speed will increase or decrease depending on the direction of the net torque applied.
That depends what you will remain constant: the angular velocity, or the speed. Here are two formulae that can help you decide: acceleration = speed squared / radius, and acceleration = angular velocity squared times radius. Angular speed should be measured in radians in this case. Angular speed is equal to 2 x pi x (revolutions per second). From the above formulae, it clearly follows that: (a) If you maintain the speed constant (and thereby reduce angular speed, a larger radius means less centripetal acceleration. (b) If you maintain the angular speed constant (and thereby increase the speed), a larger radius means more centripetal acceleration.
"Some later CD drives use CLV technology in combination with constant angular velocity (CAV). With CAV, the disc rotates at a constant speed, just as is done with hard drives."(pg 459, A+ Guide to Managing and Maintaining Your PC)
