NOTE 1 In an inertial frame, the angular velocity does not depend on the chosen coordinate system provided that the orientation of space is kept (either right-handed or left-handed).

NOTE 2 The coherent SI unit of angular velocity is radian per second, rad/s.

grandeur vectorielle axiale décrivant la rotation autour d’un axe, dont la norme est ω=| dφ/dt| MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiabeM8a3jabg2da9m aaemaabaqcLbuacaGGKbGccqaHvpGzcaGGVaqcLbuacaGGKbGaamiD aaGccaGLhWUaayjcSdaaaa@4578@ , où dφ MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaKqzafGaaiizaOGaeq y1dygaaa@3C36@ est la variation d’angle plan pendant un intervalle de temps infinitésimal de durée dt, et dont la direction est celle le long de l’axe pour laquelle la rotation est vue dans le sens des aiguilles d’une montre

NOTE 1 Dans un référentiel inertiel, la vitesse angulaire ne dépend pas du système de coordonnées, pourvu que l’orientation de l’espace reste inchangée (directe ou rétrograde).

NOTE 2 L’unité SI cohérente de vitesse angulaire est le radian par seconde, rad/s.
