Does earth's gravity do any work on satellite revolving around it?

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.)

What is earths oldest satellite?
Vanguard1
What satellite circles the earth exactly once a day?
The moon is the earths only natural satellite
How do satellites move in orbit?
Satellite orbit the Earth at different altitudes. A good overview of Low Earth Orbit, Medium Earth Orbit and Geostationary Orbit can be found here: http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
What type of satellite orbits perpendicular to the earths equator?
polar satallite
Earths gravity as a percentage?
enough to keep us on it
Why do you call the moon Earths natural satellite?
Because the moon naturally revolves around the Earth and things that revolve around each other are called satellites (ex. the planets revolving around the sun) so therefore the name "Natural Satellite".
Which planets surface gravity is 38 percent that of earths?
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
Is a moon a place or a thing?
nither it is a natural satellite held in orbit by the earths gravity. Without it we would have no tides.
Is the moon a place or thing?
nither it is a natural satellite held in orbit by the earths gravity. Without it we would have no tides.
Is moon is place or thing?
nither it is a natural satellite held in orbit by the earths gravity. Without it we would have no tides.
Is it correct to say that satellites fall back to earth falling to earth because they are beyond the pull of earths gravity explain?
That is not English; that is not physics. Generally speaking, the speed of the satellite and gravity cancel each other. As the satellite slows (friction), gravity wins.
Why moon keeps on revolving around the earth in closed circular orbit?
because of the earths gravitational pull
What is a common model for Einstein's theory of gravity?
Whatever goes up and remains within the influence of earths gravity must come down, or circle the earth as a satellite.
What is a satellite that orbits earth?
If by satellite you mean an object that orbits the earth, then the Moon is a satellite of the earth. There are thousands of other satellites put into orbit by both private and public organizations used for everything from GPS to communication and even you TV service.
Does a satellite orbit earth free from earths gravity?
No. Gravity is responsible for all 'orbits'. If there were no other body attracting it, the orbiting object would sail off in a straight line.
Where would a satellite revolving around earth land if it crashed?
It will most likely burn up through the earths atmosphere on re-entry. The satellites travel at very high speeds, and are not designed to withstand the brunt of the earths atmosphere at the speeds at which they orbit the earth. You might get some bits left over, but these should be quite small. Operators try to land the satellite in the sea once it has reached the end of its life.
Explain How is the moon earths satellite?
the moon orbits the earth and one definition of a satellite is "a natural body that revolves around a planet"
