 = −1 unit

Angular acceleration– is the exchange rate of angular velocity of the time.

ℎ
=

 =  − −2 unit

The equation of angular motion with constant acceleration :

 =  + 

 = ( +  )

 =  + 

 =  + 

-1
Where : 1 = The initial angular velocity (rad s ).

-1
2 = final angular velocity (rad s ).

 = rotation angle (rad).

T = time taken (second).

-2
 =angular acceleration (rad s ).
