Historical Examples
• Let α be the angular velocity of rotation, R the radius of the disk.

• The angular velocity of the revolving field is remarkably uniform.

Anonymous
• Descending, they gained in angular velocity as they lost height.

Murray Leinster
• The angular velocity is regulated by a Watt's governor, which secures an isochronism of the motion independently of the charge.

• The angular velocity of the axle corresponding to a speed of seven miles an hour, is 84 revolutions per minute.

• Either the orbit could not be circular, or else the angular velocity could not be constant about any point whatever.

Walter W. Bryant
• This angular velocity cannot be any portion of the medium of sensible dimensions rotating as a whole.

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.
