Angular velocity, often denoted by the Greek letter omega (ω), is a scalar measure of the rate at which an object rotates or revolves around a fixed axis or point. It quantifies how quickly an object's angular position changes over time. The standard unit for angular velocity in the International System of Units (SI) is radians per second (rad/s). It can also be expressed in degrees per second, revolutions per minute (rpm), or other units related to angular displacement and time.

The relationship between linear velocity (v) and angular velocity (ω) for an object moving in a circular path of radius (r) is given by v = ωr. This equation highlights that for a given angular velocity, an object further from the axis of rotation will have a higher linear velocity. Angular velocity is a vector quantity in more advanced contexts, with its direction indicating the axis of rotation according to the right-hand rule. However, in many introductory physics and engineering applications, it is treated as a scalar. Understanding angular velocity is crucial in fields like mechanics, astronomy, and rotational dynamics.
