Question

Dimensional formula of angular acceleration

Answer 1

Answer:

The angular acceleration is given by alpha = angular speed/time.

So it's unit is rad s^-1

Dimensional Formula : [T-2]

Answer 2

The dimensional formula of angular acceleration is, $\alpha =[LT^{-2}]$

Explanation:

We need to find the dimensional formula of angular acceleration. The angular acceleration is given by :

$\alpha =\dfrac{\omega}{t}$

$\omega$ is the angular velocity

t is the time taken

The dimensional formula of angular velocity is, $[\omega]=[LT^{-1}]$

So, the dimensional formula of angular acceleration is, $\alpha =[LT^{-2}]$

Hence, this is the required solution.
