Solution

If the angular velocity is constant, then algebraically it is defined as,
= tt
where,
is angular velocity
is the angle rotated
‘t’ is the time taken

It may be realized when the angular velocity is constant, the angular acceleration is 0. If the velocity is not constant, then the constant angular acceleration is defined as

= tt = t2t2

If the angular acceleration is not constant and varies from time to time, then we can only refer to average angular acceleration and instantaneous acceleration.

In such a case the angular acceleration formulas are,
_av = (2–1)(t2–t1)(2–1)(t2–t1) and _i = ddtddt = d2dt2d2dt2.These equations help us in finding angular acceleration.
