The ISS completes each orbital revolution of the Earth in about 90 minutes.
360 degrees/90 minutes =
-- 4 degrees of angle per minute of time
-- 4 minutes of angle per second of time
-- pi/45 radians per minute
The Earth's angular velocity vector due to its axial rotation points towards the north pole.
Hmm...angular velocity. First of all, when you talk about the universe, it seems like you are talking about an object. But the universe is a rapidly expanding object of space and time, so there should be no real boundaries. That means it can't really rotate at all. So, in conclusion, using angular velocity is not suitable for measuring what you are trying to find.
The ISS is orbiting at around 27,743.8 km/h ((17,239.2 mph)
They don't rotate in the same direction. But most of the rotation comes about from the conservation of angular momentum. Angular momentum is given by L=m*w*r2 where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion. Due to conservation of angular momentum, if the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). Hope I answered your question...

The tangential velocity is greater as the radius of the point on the rotating object increases. For a rotating object v = rw Where v is the tangential velocity r is the radius of the point And "w" is omega or angular velocity (in radians per second)
angular momentum and angular velocity
linear velocity= radius* angular velocity
No, uniform angular velocity means no angular acceleration.
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
no, velocity=displacement/time
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.
Yes, angular velocity is a vector quantity
velosity in circular path angular
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
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
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.
