theta or θ
The lowercase Greek letter "omega" is often used - it looks like a rounded "w". (When this symbol is used, angular velocity is usually specified in radians per second.)The lowercase Greek letter "omega" is often used - it looks like a rounded "w".

There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
The angular velocity of the second hand of a clock is pi/30 radians per second.
Letω = angular speed (we can't do velocity with the given information),f = frequencyω = 2π fω = 2π (50 * 1000 Hz) = 100,000π rad/sec ~= 314,159 rad/spec
theta or θ
no, velocity=displacement/time
No no its a true vector for infinite angular displacement
No no its a true vector for infinite angular displacement
Radian is the unit for angular displacement is SI system of units.
angular displacement is a vector quantity when theta (angle) is small, otherwise it is scalar.
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.
Radians
It is the rate of change - with respect to time - of the angular displacement.
These are used in lots of engineering problems related to rotation.
Here's the easiest answer: They have different names.....
Angular displacement is a vector quantity because it has both magnitude and direction. The direction of angular displacement is determined by the axis of rotation and follows the right-hand rule, while the magnitude is given by the angle of rotation. As a vector, angular displacement can be added, subtracted, and resolved into components, making it useful in calculations that involve rotational motion.
