angular velocities

Noun

angular velocity (countable and uncountable, plural angular velocities)

1. The angle turned, per unit time, by a body rotating about an axis; the rate of rotation through an angle.
   • First, we have the angle θ which defines how far the body has gone around; this replaces the distance s, which defines how far it has gone along. In the same manner, we have a velocity of turning, ω=dθ/dt, which tells us how much the angle changes in a second, just as v=ds/dt describes how fast a...1963, Richard Feynman, The Feynman Lectures on Physics (1963) Ch. 18 Rotation in Two Dimensions, 18–2 Rotation of a rigid body.
