What is Difference between angular velocity and angular speed?
Angular velocity refers to the rate of change of angular displacement with respect to time and has both magnitude and direction. Angular speed, on the other hand, refers to the rate of change of angular displacement with respect to time but does not consider direction and is scalar in nature. In simpler terms, angular velocity includes direction while angular speed does not.
What are the dimensions of angular velocity and how are they calculated?
Angular velocity is a measure of how quickly an object is rotating around a fixed point. It is typically measured in radians per second (rad/s) or degrees per second (/s). The formula to calculate angular velocity is angular displacement divided by the time taken to make that displacement.
What is the symbol for angular velocity?
The symbol for angular velocity is ω (omega). It represents the rate of change of angular displacement of an object rotating around an axis.
What are the dimensions of angular displacement?
Angular displacement dimensions are radians. There are ( 2 ) ( pi ) radians or 360 degrees in one complete circle of displacement. Some treat angular displacement as having no dimensions; however, this is a poor and misleading practice. Angular velocity commonly has dimensions of rad/s or radians per second.
Relation between linear velocity and angular velocity?
Linear velocity is directly proportional to the radius at which the object is moving and the angular velocity of the object. The equation that represents this relationship is v = rω, where v is the linear velocity, r is the radius, and ω is the angular velocity. As the angular velocity increases, the linear velocity also increases, given the same radius.
Solution and answer of angular velocity?
It is the rate of change - with respect to time - of the angular displacement.

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.

What is the Relation between angular velocity and frequency?
If there is a rotation, "angular velocity" and "angular frequency" is the same thing. However, "angular frequency" can also refer to situations where there is no rotation.
Relation between linear velocity and angular velocity?
Linear velocity is directly proportional to the radius at which the object is moving and the angular velocity of the object. The equation that represents this relationship is v = rω, where v is the linear velocity, r is the radius, and ω is the angular velocity. As the angular velocity increases, the linear velocity also increases, given the same radius.
What is ment by angular momentum and angular velocity?
Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.
How is angular velocity related to tangential velocity?
The time, T , it takes for an object to go thru one comblete rotation of 360 degrees or 2pi radians is its "period." The rate at which it completes the rotation is its "angular velocity." The rate is the angle (in radians) divided by the time. So , Angular Velocity = 2 pi / T.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
