*omega-squared* **=** *omega-sub-zero-squared*
plus *two-alpha* times *delta-theta*

This is one of the constant **angular**
acceleration equations. It's the one with no "*t"*
in it.

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

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.

delta-thetaisthetaminustheta-sub-zero. It is the angular displacement from time 0 to timet.

**Note**: "Angular Motion" is
synonymous with "Rotational Motion". In the discussion
of rotational motion, the words "angular" and
"rotational" are interchangeable except in the case of
the rotational inertia I which is referred to as
"rotational inertia" or as the "moment of
inertia" but is not referred to as "angular
inertia".

**Tip**: In a constant angular acceleration
problem, list the variable names with their values and the sought
quantity with a question mark. Use the constant angular
acceleration equation that is missing the variable not listed.
