| 释义 | > as lemmasangular speed angular speed n. the rate at which an object rotates around a point, measured in revolutions, degrees, or radians per unit of time.Unlike angular velocity, the angular speed does not specify the direction of rotation. ΚΠ 1840 Mem. Royal Astron. Soc. 11 255 The first [investigation] is..into the motion of governor-balls, supposed to be acted on by no force; for the purpose of deducing the time of rotation corresponding to a given angular expansion of the balls, and the periodic time of their oscillations, and the consequent oscillations in the angular speed of the spindle. 1929 Physical Rev. 34 1464 The angular speed of the disks averaged 3600 R. P. M. 2014 S. T. McCaw Biomech. for Dummies ix. 163 Angular speed is not frequently calculated in biomechanics, because specifying the direction of the angular motion is usually as important as specifying how fast rotation occurs. < as lemmas |
