Answer:
angular momentum is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.
Explanation:
net external torque = Inertia x Angular Acceleration
this is newtons second law of rotation
f = ma
rf = rma
rf = rmra
rf = r^2ma
t = i a
where r is radius of the circle
i is inertia
a is angular acceleration
