What is Angular Speed?
Angular speed is how fast the central angle changes in respect to time. Below you will see an angle that is changing by θ distance.
With this in mind, you can now define the angular speed of any given angle.
angular speed=centralangletime You can then abstract this out even one more step by using θ angle with t time.
angular speed=θt
Remember all that θ is the value of the arc divided by the radius. See "How to find theta of any given angle?"
