    Why is "L" the angular momentum

    I was wondering why is L used as the symbol for angular momentum? :bugeye:

    Because the scientist that discovered it was sick and tired of using Greek symbols and said, "Hmmm, a random letter... l. But l's taking, so we'll use L."
    Atleast, that's what I think. :D

    There's no (or at least i haven't heard/read of a) justification...Merely a convention.You could ask why we denote the coordinates by x,y,& z instead of d,h,& k... :wink: Sometimes there is,sometimes there isn't an explanation...
