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.

How can explain inertia governor?
Centrifugal governors respond to angular velocity. Inertia governors respond to angular acceleration.
Explain how distance time and velocity are related to each other?
They are related through the formula distance = time x velocity (assuming constant velocity).
Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
Explain why you don't do any work when you carry an object at a constant velocity?
because it stays the same
Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
Explain why velocity changes while driving around a circular track even if the speed is constant?
Velocity consists of a speed and a direction. If any of the two changes, the velocity changes.
Explain the term angular velocity?
Angular velocity is a measure of how fast something is spinning. It can be measured as either degrees per second or radians per second. 1 turn per second would be 2 PI radians per second or 6.283185... rad/sec or 360o /sec
Can your body sense constant velocity and explain?
Your body cannot sense constant velocity. For example, you cannot sense that the earth is turning nor can you sense that the earth is orbiting around the sun. And, if you are in a vehicle that is traveling with a constant velocity, you cannot sense that you are moving unless your eyes sense a change in position.
How do you explain streamline flow?
a fluid in which ita velocity at any point is constant or varies in a regular manner.
If the speedometer of your car reads a constant speed of 40km per hour can you say 100 for sure that the car has a velocity explain your answer?
Ok but did I ask?
Define constant angular velocity and explain how it applies to CD standards?
Constant angular velocity of a rotating disk means that, given a stationary base reference line and a zero line on the disk, both extending from the center of rotation to the outside edge of the disk, the periodic change in angle between the two lines remains a constant. Such a disk will have constant angular velocity (CAV) if its rate of rotation or revolutions per minute (RPM) remains constant.While it would be technically possible to have the linear velocity of the disk remain constant by gradually decreasing the speed of rotation as the player head moves across the disk (because the outer paths are longer than the inner ones), this would make things more complicated both for the recording and playback machines, and therefore more expensive.The paths of information on a CD (or DVD) are analogous to the grooves on an LP recording. The recording and playback heads move across the disk (CD or LP) as it rotates. Actually, of course, there is only one spiral path or groove; on an LP, it goes from the outside edge toward the center; on a CD/DVD, it goes in the opposite direction. In deciding on the parameters for the LP and CD, engineers had to involve the amount of data to be recorded and the spacing required to record that data versus the size of the disk, the speed of rotation, the data capacity of the disk material, and the sensitivity of both the recording and playback heads.The result of this engineering was set as the standard for recording audio LP's and CD's and, later, DVD's.
Explain whether a car can move with changing velocity while maintaining constant speed?
Velocity is a quantity that has magnitude and direction. The magnitude of velocity is what we call "speed".If the velocity is constant, then its magnitude and direction are both constant.Constant magnitude means constant speed.So the answer to the question is "Yes".
