Why is L the angular momentum

Click For Summary
The symbol "L" is used for angular momentum primarily as a convention, with no formal justification behind the choice. One humorous suggestion is that it was selected because the letter "l" was already taken, leading to the use of "L" instead. Another participant pointed out that "L" relates to the term "Angular" in angular momentum. The discussion highlights the arbitrary nature of scientific notation, comparing it to other symbols used in physics. Ultimately, the choice of "L" remains a matter of convention rather than a deeply rooted rationale.

Why is "L" the angular momentum

I was wondering why is L used as the symbol for angular momentum? :bugeye:
 
Physics news on Phys.org
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...

C'mon! It's so OBVIOUS! L, as in AnguLar momentum.

Jeez...

:biggrin: :smile:
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
