*omega* **=** *omega-sub-zero*
plus *alpha* times *t*

This is one of the constant **angular**
acceleration equations. It's the one with no "*theta"*
in it.

omega[radians-per-second] is the angular velocity of the object at time t.

omega-sub-zero[radians-per-second] is the angular velocity of the object at time 0.

alpha[radians-per-seconds-squared] is the angular acceleration.

t[seconds] is the time.

Tip: In some problems you need to use *Newton's Second Law
for Rotational Motion*, "Torque is equal to I times*
alpha*" to get *alpha* before you can apply one
of the constant angular acceleration equations.

**Pitfall Avoidance Note:** The
units for alpha are **not** m/s^{2}.
