	Angular velocity - Wikipedia, the free encyclopedia
		The magnitude of the angular velocity is the angular speed (or angular frequency) and is denoted by ω.
		With constant angular acceleration, the angular velocity conforms to the rotational equations of motion, equivalent to the standard linear equations of motion under constant linear acceleration.
		In the case of pure circular motion, the angular velocity is equal to linear velocity divided by the radius.

		is sometimes used as a synonym for the vector quantity angular velocity.
		Angular frequency is therefore a simple multiple of ordinary frequency.

		Linear velocity gives the number of meters the mass travels in a second, while angular velocity gives the number of revolutions of the mass in a second, regardless of big a circle it travels around.
		Degrees are a unit of angular measurement, and though we have defined angular velocity as the number of revolutions per second, the term "angular velocity" itself suggests it's more properly defined as the change in angle per second.
		The angular velocity is the same in both places, but the actual linear speed along the circular path is very much greater at the equator, since the distance between Dexter and the Earth's axis of rotation is very much greater as well.

		The reduced ball velocity of TP subjects with lesions at the C7 to C8 levels depended on an insufficient wrist flexion angular velocity, where dysfunction of available musculature may be a causal determinant.
		As shown, the maximum values of angular velocity of shoulder abduction and elbow extension were found to occur prior to ball release, whereas that of the wrist joint occurred at ball release.
		The interpretation is that the reduced ball release velocity (vertical component) of the TP subjects depends primarily on an insufficient wrist angular velocity in which dysfunction of the wrist flexor muscles may be a causal determinant.

	Forum Thread : Local Angular Velocity :. GarageGames
		I'm not sure if the angular velocity in the rigid body class is a direction vector (axis for the rotation) and the magnitude is the actual units per second or if it's actual changes in orientation per axis.
		The 3 floating point units for the velocity vector define the axis of rotation and the magnitude is the angle/second.
		I'm not sure what way you were integrating the angular velocity, but it's possible that you were not getting accurate results as this is actually a result of the angular momentum being transformed by the inverse inertial tensor (or mass moment of intertia if you like) in world space.

		The linear velocity of the head of the club at impact is equal to the angular velocity of the club at impact multiplied by the distance of the head of the club from the axis of rotation of the club.
		One way to increase the linear velocity of the club head is to keep the angular velocity the same and increase the length of the axis of rotation by choosing a longer club.
		The angular velocity of the club at impact is determined by the angular acceleration of the golf club throughout the swing.

		If a force acts tangential to the wheel to speed it up, it follows that the change in angular velocity and therefore the angular acceleration are in the direction of the axis.
		The angular momentum will also be in this direction, so in this example, all of these angular quantities act along the axis of rotation as shown.
		The change in angular momentum is therefore along the axis and the wheel increases in angular velocity.

		Since the waveforms of head position and velocity differed in shape and frequency content, the particular head position and angular velocity sensitivity of otolith-ocular responses could be independently assessed.
		During both constant velocity rotation and low frequency sinusoidal oscillations, the otolith system generated two different types of oculomotor responses: (a) Modulation of three-dimensional eye position and/or eye velocity as a function of head position relative to gravity, as presented in the preceding paper.
		Higher head velocities resulted in saturation and a decrease in the amplitude of the steady-state response components during constant velocity rotation and in increased phase leads during sinusoidal oscillations.

	Angular velocity \| International Meteor Organization (Site not responding. Last check: 2007-11-05)
		Thus the apparent angular velocity omega of a shower meteor (in degrees per second) can be calculated by the framed formula below depending on the pre-atmospheric velocity V_infty (km/s), the elevation h_b (degrees) and altitude H_b (km) of its start point, and the angular distance between its end point and the radiant D_e (degrees).
		From this geometric situation we can determine the angular velocity omega of a shower meteor with a known atmospheric entry velocity V. With l being the apparent path length of the meteor and s its true trail length.
		The angular velocity omega of a shower meteor is thus well defined for any point in the sky.

		The direction of this velocity is constantly changing, but at any instant it points in a direction tangent to the circle (and perpendicular to the radius).
		The magnitude of this velocity is related to the radius r and the angular velocity
		This is because velocity is a vector, and so a change in direction is a change in velocity, and acceleration is the change in velocity per change in time.
