# angular velocity

## noun

, Physics.
1. the time rate of change of angular position of a rotating body, usually expressed in radians per second or radians per minute.

angular velocity

## noun

1. the velocity of a body rotating about a specified axis measured as the rate of change of the angle subtended at that axis by the path of the body ω

angular velocity

1. The rate of change of an angle associated with an object with respect to some reference point. For example, the average angular velocity of an object moving around a central reference point once every second is 2π radians per second; the Earth spins around its axis with an angular velocity of 2π radians per day.
2. Also called angular frequency
