Definition

vector (ISO 80000-2: Mathematics) quantity giving the rate of change of angular velocity (angular velocity)

grandeur vectorielle donnant le quotient de la variation d'une vitesse angulaire (angular velocity) par la durée de cette variation

Notes

The angular acceleration vector is given by:

α = \frac{d ω}{d t}

Where $ω$ denotes the angular velocity (angular velocity) and $t$ the duration (duration).

Le vecteur accélération angulaire est donné par:

α = \frac{d ω}{d t}

où $ω$ désigne la vitesse angulaire (angular velocity) et $t$ la durée (duration).
