Radians/second2.
Newton
No, uniform angular velocity means no angular acceleration.
Angular acceleration is a vector.
Angular acceleration is the trate of change of angular velocity, often represented by the letter alpha.
No. Acceleration and speed are related in the same way irrespective of being linear or angular. Acceleration is rate of change of speed.
Yes. A ngular acceleration is to do with something turning. Radial acceleration is linear acceleration perpendicular to the angular acceleration.
Angular Measure
Assuming you mean "phase", it is usually expressed in angular units - degrees, or radians.

Since angular acceleration is in radians per second squared, which is change in angular speed over time, we know that α=ω/t, where α is angular acceleration, ω is angular speed, and t is time (assuming α is constant.)ω is measured in radians per second. If me multiply ω by r, which is the radius of the circle the object is acceleration around, we get ωr, which has units of (radians*radius)/second. Since the angle in radians times the radius gives the distance, these units are equivalent to meters/second, so ωr = v.Therefore, α=(v/r)/t=v/rt.Acceleration (a) is v/t, so α=(v/t)(1/r)=a/r.The equation would then be:α=a/r, or a=rα (Where α is angular acceleration, a is acceleration, and r is the radius.)
angular acceleration
Angular impulse is defined as the rate-of-change of the angular acceleration.
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
