it maintains a feeling of earths gravity, right?
Same effect as on planet earth.
Then is it safe to say gravity is like a constant acceleration?

Yes. You have arrived at the same conclusion that Einstein did.

IF you are standing on the same spot on Earth for a Significant Moment, then the gravity you feel is a constant acceleration, toward the Earth's center.

With the advent of relativity, that is exactly how gravity is described. The effects due to acceleration, (inertia) and gravity are indistinguishable. Standing still on the earth, it could be said that you are accelerating at a constant 32 ft/sec^2 in the earth's gravitational field, without actually moving. In your space ship, you are accelerating due to motion without being in a gravitational field.

Yes, exactly.
This is called the "Einstein's equivalence principle". If you are in a closed room, with all the instruments you want but no way to see out, there is no way to tell if you are on Earth or in a spaceship accelerating at 1 G.
(Assuming that the spaceship engines don't vibrate, and that there are no other clues like that.)

I don't know if I would call it constant acc. But gravity Is a constant. And no, if a space ship keeps accelerating it would not maintain a feeling of earths gravity. For instance the space shuttle , when in space travels anywhere from 15.000 to 25.000 mph. and there are no "G'' forces exerted on the astronauts inside. "G" forces are a rating of the earths gravitational pull on anything at any given time. But in space there is no gravity until you near a large enough body, which exerts gravity on said ship.
But then again I'm just a layman.

Every Object on this planet has a free fall acceleration of 9.81ms-2, so therfore it will be constant, yes, as long as it is within the Earths Gravitational pull.

Yes, it is. Scientists often speak of the acceleration of gravity.

Ignore scotty w, he doesn't know what he's talking about. Astronauts do indeed feel g forces when they are accelerating.
