Angular velocity or speed has formula :-
angular velocity=Linear speed/radius.
Formula of angular momentum (L) :-
1) L = mvr
2) L = I ( capital i ) * angular velocity.
use first formula to find the angular momentum of a point mass object about an axis,
Second formula for a Rigid uniform body.
In first formula,
m:- mass of point object.
v :- it's Linear velocity.
r :- shortest distance ( i.e. shortest distance) of the point object from the axis or point about which angular momentum is calculated.
In second formula,
I :- moment of inertia (I) of that Rigid body About the fixed axis who's L is to be calculated about that axis.
please feel free to ask if you don't know about moment of inertia.... or have any other doubts
