angular velocity

noun, Physics.

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

Origin

Examples from the web for angular velocity

The mistake is that the astronomers by autistic mathematics have mixed up orbital speed and angular velocity.
The angular velocity of stars is remarkably constant across the galactic radius.
Their angular velocity remains independent of gravitational attraction even though gravity maintains them in orbital motion.
Convention puts the angular velocity vector along the axis of rotation.
The arrow pointing up on the axis of rotation of the merry-go-round is the angular velocity vector for the platform.
angular velocity is how fast you rotate and acceleration relates to how much change in movement you feel.

British Dictionary definitions for angular velocity

angular velocity

noun

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 in Science

angular velocity
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. Also called angular frequency.

Encyclopedia Article for angular velocity

time rate at which an object rotates, or revolves, about an axis, or at which the angular displacement between two bodies changes. In the , this displacement is represented by the angle theta between a line on one body and a line on the other
