The angular acceleration is given by:
α = dω / dt = d2θ / dt2 = ar/R

Where we have:
ω: angular frequency
ar: linear tangential acceleration
R: the radius of the circle
t: time

The angular acceleration can also be determined by using the following formula:
α = τ / I
τ
: torque
I: mass moment of inertia or the angular mass
