[[Angular Displacement|Angular displacement]] is the angle through which an [[object]] in [[Circular Motion|circular motion ]] has turned in a given [[time]].

*[[Measure]]d in [[radiansradian]] s (rad).*Represents the change in position of an [[object]] along a circular path.Positive for *As the quantity has direction it may be positive or negative, but once decided that clockwise or anti-clockwise rotation is positive the other should be negative.*[[Angular Displacement|Angular displacement]] can be calculated using the arc length divided by the radius.*It is a vector quantity, having both magnitude and negative for clockwise rotationdirection.*[[Angular Displacement|Angular displacement]] is an essential parameter in rotational kinematics.*[[Angular Displacement|Angular displacement]] is used in calculating other rotational quantities like [[Angular Velocity|angular velocity]]. 

*The hands of a clock show [[Angular Displacement|angular displacement]] as they move.*[[Earth]]’s rotation involves [[Angular Displacement|angular displacement]] of 2π [[radiansradian]] s in 24 hours.
