The angular acceleration is given by:
α
= d
ω
/ d
t
= d
2
θ
/ d
t
2
=
a
r
/
R
Where we have:
ω
: angular frequency
a
r
: 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
