Yes, you have a point.
Angular momentum is called... err... wait, it's coming... err...
it's on the tip of my tongue, bear with me... err... let me think...
err... yes, I have it...it's called "glosipnurt", Pokefield.
That makes it different to "momentum", it is "something else".

Really, whether one calls a football a ball or a dance a ball, a ball
is a ball is a ball. "We" should call it a ball, and "we" do.
"You" need to learn what "we" mean, Pokefield, "we" are not
changing English to suit other people, but just for you (as a
very special person), angular momentum is called "glosipnurt"
by my decree.
Please refer to non-mv as glosipnurt in future correspondence.

Sorry. You missed the point. Angular momentum is correct: it is the
momentum mv of an object whose motion is not rectilinear.

Erm....isn't it more like I * omega, where I is the moment of inertia
and omega the rotation speed?
