Which satellite are you referring to ? Satellites stay in orbit because the force trying to 'throw them out into space' is counter-balanced by the gravitational pull of the earth. Those that are revolving round the planet (as opposed to geostationary ones) do so, because they were set in a side-ways motion when they were launched.
They do fall. But they're traveling fast enough so that the surface of the Earth falls away from them as fast as they are falling. Same thing that keeps the Earth from falling into the sun.
Gravity, you idiot!
Yes, if they were stand still and were not revolving around each other! The Centrifugal force of Moon's revolution around Earth keeps them apart
because the earth's gravity keeps it in place
The satellite is pulled towards the Earth by the force of gravity, but it also has it own high velocity in its orbit. As it accelerates downwards towards the centre of the Earth, its velocity keeps track of the Earth's curvature, so it actually stays at the same height constantly.
NO. The gravity of Earth, in conjunction with the inertia of the satellite, keeps the satellite revolving around Earth. However, the satellite doesn't get any nearer to the Earth. So, according to the laws of physics, no work is done. (I'm ignoring the fact that satellites sometimes lose height and need to be "boosted" a bit to maintain their orbits. Also, I'm assuming that the satellite's orbit is circular. If the orbit is elliptical the answer is more or less the same, but a bit more complicated.)

They do fall. But they're traveling fast enough so that the surface of the Earth falls away from them as fast as they are falling. Same thing that keeps the Earth from falling into the sun.
Gravity.

because of the earths gravitational pull
There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
Then it would fall into the Sun. It is the Earth's movement (of about 30 km/second) that keeps it from falling INTO the Sun.
Gravity, you idiot!
gravity
the gravitational force of earth keeps the satellite(better write artificial satellite)in orbit.
The velocity of the satellite along with the earths gravitational pull work together to keep a satellite from either flying out into space or burning up in the atmosphere. They have to launch a satellite at a precise speed to make sure that the speed at which the satellite falls to earth matches the earth's curvature. The speed is 8000 meters a second.
