# What is Dimensional Formula of Angular Acceleration?

Posted in Dimensional Formulae | Email This Post |Angular Acceleration is defined as change in angular velocity per unit time . Its formula is

**Angular Acceleration = Angular velocity / Time**

Dimensional Formula of Angular velocity = M^{0}L^{0}T^{-1} Divide it by Time T^{1}

**So Dimensional Formula of Angular Acceleration = M ^{0}L^{0}T^{-2}**

SI unit of

**Angular displacement**

**is rad s**

^{-2}
wow

thanks a lot
