This is the object's resistance or inertia to changes in its angular motion.
Stellar rotation is the angular motion of a star about its axis.
This additional angular motion imposed by the field is quantised, exactly as if the electron was constrained in an orbit around an atom.
With a jerry-rigged sextant and their wristwatches, they timed the angular motion of the setting Sun.
Further, they can be observed with radio interferometers which can measure very small angular motions.
This angular motion is quantified by the angular velocity vector.
And that would imply a far greater angular motion of the centre than Dr. Marlowe says has taken place.
In frame S the radial motion is constant and there is no angular motion.
Danzas nodded his head, a curiously angular motion like the bobbing of a child's toy.
By measuring the difference in capacitance between the two tines of a fork, the system can determine the rate of angular motion.
