*Describes the rotational [[speed]] of an [[object]].
*Different from linear [[speed]], which measures movement along a straight path.
*[[Angular Speed|Angular speed]] can be calculated by dividing the [[angular displacement]] by the [[time]] taken.
*[[Angular Speed|Angular speed]] is a [[scalar]] quantity, representing the magnitude of the rotational motion.
*[[Angular Speed|Angular speed]] is constant in uniform [[Circular Motion|circular motion]].
*[[Angular Speed|Angular speed]] is related to the [[Speed|linear speed]] by the equation v = rω, where r is the [[radius]] of the circular path.
===Formula===
v = rω
Where:
v is [[Angular Speed|angular speed]]
r is the [[radius]] of the circular path being followed
and
ω is the [[Angular Frequency|angular frequency]]
===Examples===
*A rotating fan blade has a constant [[Angular Speed|angular speed]].
*The [[Angular Speed|angular speed]] of [[Earth]]’s rotation affects the length of a day.
