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

Example Sentences

Gyroscopes are devices used to detect and measure changes in orientation or angular velocity -- the rate at which an object rotates.

From Science Daily

From New York Times

The sensors include “accelerometers to measure acceleration, gyroscopes for angular velocity and rotational speeds and magnetometers to measure direction,” the Fresno Bee explains.

From Salon

A commission said that failure was caused by the improper installation of three angular velocity sensors.

From The Guardian

Close registration between the gears ensured that both hindlegs moved at the same angular velocities to propel the body without yaw rotation.
