Zero-G is a misnomer. Gravity gets weaker with distance, but it never falls all the way to zero. You cannot "escape the bounds of gravity" anymore than you can escape the grasp of the IRS. Astronauts look like they are experiencing no gravity because they are orbiting the Earth. What they are really feeling is freefall. In effect, they are falling toward the Earth, but moving sideways enough to continuously miss it. The net result is they follow the curvature of the Earth, always falling but never hitting.
At the typical shuttle orbital height of 250 miles (400 kilometers) off the Earth's surface, the force of gravity is roughly 90 percent what it is here on the surface. Gravity is still very much in control of the shuttle's (and astronauts') motion. Inevitably, when they land, they return to its full effects.

Kev ... No, you would not FEEL gravity if you're not accelerating (or decelerating) because you and everything around you are traveling in unison and "falling" around the Earth together (presuming you were in Earth orbit). But a previous answer you received indicated there is no gravity in space. Sorry, but that is not correct. If there was no gravity in space, the Moon would not orbit the Earth and you and your spacecraft would not orbit the Earth, either. Once gravity were "turned off," for lack of a better term, your circular path around the Earth would cease and from that moment forward, you'd begin to travel in a straight line AWAY from the Earth on a tangential path.

If you mean like being in a rocket, the answer is yes. The "G" in G-force stands for gravity. Gravity is an acceleration as given by Newtons equation: F=ma. If you are in a rocket in space at rest then fire the engines, the particles of gas leaving the the rocket have momentum in a given direction, lets call that direction "x." By the law of conservation of momentum, since we started at rest, that is the inital momentum was zero, the rocket must move in the other direction, "-x" to keep the net momentum as zero. Now, you are inside the rocket. When it starts to move, it starts slowly and gets faster, that is an acceleration. The rocket will push on you since you started at rest as well. It's like being in a car at a red light. When the light turns green and the car starts to move, you press back into the seat a bit. Or when you go around a turn, you press against, or lean, in the opposite direction that the car is turning. You are actually trying to keep moving in a straght line, but the car pushes you around the curve with it.

You would feel the so called G Force if you acclerated or slowed down. It's got nothing to do with gravity as such. The term G force is just a way of describing how heavy you feel in certain situations (like sudden acceleration in a car) compared with how heavy you feel whilst 'stationary' relative to the earth. If you were sitting in a space ship and it accelerated, you would feel yourself being pressed back into your seat and would experience a sense of weight.

You would still feel forces due to acceleration. Even in outer space, Newton's law F = ma still applies.

G-Force is just the term of how many multiples of the acceleration of gravity one feels.

So yes, if you are being accelerated at 29.43 m/s^2 in outer space, you would feel 3 G's.

Yes as any change of state of position needs a push and the more you are pushed the more G force you will feel and it doesnt matter wether you are in zero G or on a planet with a higher G than earth, you should read Newtons theorems about motion .

sigh, there is gravity everyhwere, you never escape it, you never experience zero g.

you freefall exactly the same as a roller coaster as it shoots down that steep hill. the astronauts are in freefall around the earth. if their ship accelerates they definitely feel g-forces. if their ship can accelerate fast enough the g-forces could equal that g-force on earth, and they would, in effect, have gravity.

yes you do.

say you were sat strapped in a seat on a space ship. if you were travelling at just 30mph and braked to zero, what would happen?

exactly the same as it would on earth you would fly forward, beacause the ships stopped movin but you haven't.

say you were travelling along in a straight line at a decent speed, then the ship took a sharp turn to the right. what would happen?

the ship goes right your body carries on going in a straight line but of course you get pulled along with the ship hence feeling g-force.

it does not matter whether you are on earth or in space.

na mate, not in space as there is no atmosphere and no light as well as no gravitational force- hence u would float. however trying to escape the earths atmosphere during take off is when u would experience utter G force. u know virgin r doing holidays in space - why not start saving?
peace man.

I would have said NO to this one as there is no resistance in space so you'd just float and feel no effects at all
