What would happen if our moon were, say, 50,000 miles away instead of
248,000 miles away?

It would fall to Earth and no longer be in orbit.

No, it wouldn't.

Moons velocity is a kilometer per second, give or take.

At 1 kilometer per second with the mass it has,
it is moving too slow to keep an orbit at that altitude.

It's too slow for a circular orbit of that radius. That's
why the orbit would end up being elliptical. It would follow
a path that took it even closer to the earth (speeding up
in the process) but still far from actually crashing into
the earth.

Ok,
I admit, I was wrong about it falling
:)
But if it did not do such (closer) "behind" the Earths direction
around the sun, It would fly away instead as the Earth
moved forward in it's motion.
(at least you are showing the physics explanation this time
without resorting to math only like others have Randy)
:)


This point has already been made in this thread.

Not "physics" wise like you did.
They took the math approach that is not "physics"
and it mathematics only.
:)
Thanks for actually thinking about physics without the math Randy.
:)
