## Main Question or Discussion Point

I'm taking dynamics of rigid bodies, I'm having some trouble with impulse and momentum.

Basically ,I know that angular momentum abt. a point ,is the linear momentum multilied by the moment arm .

BUT ,I'm not feeling at all comfortable appliying it

For example , When is H abt. a pt. p = (moment of intertia abt. p )(w) and when is it m*V*d ,and when is it Ig*w +mVg *(d) ,i'm very confused about the whole thing and when to apply what so any clarification on the subject would be very helpfull , preferably I would like the most general case stated and explained,than when to cancel out terms and why to get to more specific cases .....

ANY clarification/comment can be helpfull

Thanks
