That is analogous to linear speed and velocity, but for rotation. Whereas a linear speed (or velocity) is expressed in meters per second (or some other units of distance / time), the angular speed or velocity is expressed in radians / second (or some other units of angle / time).
Of course, when something rotates, there is also a linear speed, but different parts of an object rotate at different linear speeds, whereas the angular speed is the same for all parts of a rotating object - at least, in the case of a solid object. For example: the Earth rotates at an angular speed of 1 full rotation / day. The linear speed at the equator is approximately 1667 km/hour; close to the poles, the linear speed is much less.

What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
Is angular speed a vector?
Scalar. Angular frequency vector is roughly synonymous with angular velocity.
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).
Consists of an objects speed and direction?
angular velocity
What are the practical applications of Angular Speed Angular Displacement Angular Velocity and Angular Momentum?
These are used in lots of engineering problems related to rotation.
With constant velocity the disc rotates at a constant speed?
Angular
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 do you find out the direction of angular accelaration?
The direction of angular acceleration comes from whether the angular speed of the object is clockwise or counterclockwise and whether it is speeding up or slowing down.The direction of the angular acceleration will be positive if the angular velocity is counterclockwise and the object's rotation is speeding up or if the angular velocity is clockwise and the object's rotation is slowing downThe direction of the angular acceleration will be negative if the angular velocity is clockwise and the object's rotation is speeding up or if the angular velocity is counterclockwise and the object's rotation is slowing downThe angular acceleration will not have a direction if the object's angular velocity is constant
What is the difference between angular velocity and angular momentum?
angular momentum and angular velocity
Relation between linear velocity and angular velocity?
linear velocity= radius* angular velocity
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
What are facts about speed?
speed is not a vector. Velocity is a vector. speed can also be used for angular velocity (which is a vector). Speed is sort of a catch all word that can cover all poorly defined velocities.
