The Moon's path foreward has nothing to do with its angular momentum. Do you know what angular momentum is, Clare?
 Quoting: Menow 935048





"where r is the particle's position from the origin, p = mv is its linear momentum, and × denotes the cross product."
[link to en.wikipedia.org]

But just geometrically this means:

We only need to see the directions to understand where "spin on an axis" can get confused in your minds.

You are picturing the effect of the rotation; I am talking of if there's rotation relative to its immediate direction (i.e., relative to the Earth, having already eliminated other bodies -- there it will seem to spin, but it is not properly understood that way).

In relation to its immediate direction, there is no extra angular shift. Hence, over the total path, no spin in its own right. It spins around the Earth, and the total angular shift is a "spin around its axis" in only the loose sense of a secondary phenomenon which you can model: the angle-shift along its axial path forward.

If it spun truly, properly speaking, then around the Earth (its relative spin-point) it would show different faces.

It would take more of a turn than its path indicates.

How does something spin relative to itself, Clare? That is total nonsense!
 Quoting: Menow 935048


Idiot.

I said reducing all other motions to static and CONSIDERING only the motion of the Earth-Moon around themselves (no motion around the Sun) or even better, imagining the Moon stopped relative to the Earth, you would NOT SEE THE MOON STILL SPINNING.

Venus, you would, if you imagined it not moving forward on its immediate path.

You can't be so confused yourself; you must be trying to confuse others.

The Moon it's in 'forward motion', Clare. It's in AN ORBIT!
 Quoting: Menow 935048


Of course it is. (Said so many times, duh.)

Its actual rotation is round the barycentre as an axis, not its own.

But since its axis turns as it goes forward, you could call this turn "spinning on its axis" if you remember what you are talking of: forward motion relative to the Earth.

Since it always faces forward relative to the next point it gets to in its orbit of the Earth, it does not have proper spin on its axis, all things (including its axial movement in orbit) otherwise being static for the moment.

So, it does not give off more direction than its path needs, along its orbit.

I will leave any more meaningless gobbledygook from you as though it were never said.

***For others:

RELATIVE TO ITS PATH, AT ANY GIVEN POINT, IT TURNS ONLY SO MUCH AS THE PATH TURNS, NO MORE. Hence, no spin relative to itself, ALL OTHER THINGS BEING STATIC.***
