With constant velocity the disc rotates at a constant speed?
Angular
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.
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.
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.
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.
If a particle moves in circle with constant speed its angular momentum about the center of circle?
The angular momentum is a constant.

How do you change the speed without changing the angular momentum?
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.
Question about linear speed and angular speed?
what is the relation angular speed and angular speed with clutch disc plate
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.
If a net torque is applied to an object that object will experience which of the following a constant angular speed angular acceleration or an increasing moment of inertia?
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.
If you increase the radius of circular motion then what is the centripetal acceleration?
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.
With what kind of constant velocity the disc rotates at a constant speed?
"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)
