Angular speed via constant angular acceleration and time
========================================================

If a body is rotating around a fixed axis with constant angular acceleration, its angular
speed is a linear function of time.

**Conditions:**

#. The axis is fixed.
#. Angular acceleration is constant, i.e. :math:`\frac{d \alpha}{d t} = 0.`

**Links:**

#. `Wikipedia, first out of the last four equations in the paragraph <https://en.wikipedia.org/wiki/Kinematics#Acceleration_2>`__.
