Yes - usually. The reason for this is that doing this requires less energy to launche them, since the launching rocket will use the Earth's rotation.
No satalite not move on same diraction of earth
a weather satellite and it rotates around the Earth at the same rate and in the same direction that Earth revolves so it is always fixed over the same location.
it's hot. ;)

A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time.
A satellite and space probe both orbit Earth (sometimes in geosynchronous orbits).

For a satellite to stay in one place over the earth, the satellite must be going in orbit in the same direction that the earth spins. The satellite must also travel at the same pace/speed as the earth spins to give us the 24-hour day that we as people witness. To apparently stay in one place it must be in a synchronous orbit. For the earth this is about 24,000 miles altitude. It must also be an equatorial satellite.

Satellites are able to travel around the earth by virtue of a phenomenon called centripital force (centrifugal force is a misnomer to the opposite effect). Imagine, an object traveling in one direction will continue to travel in that direction at the same speed unless acted on by a force (Newton cleared this one up for us with some degree of confidence). So if a satellite is launched into space the earth's gravity is going to pull it back toward the earth, however since the satellite is already traveling at such great speeds in a path that has been determined so that the velocity of the satellite always manages to be perpendicular to the force of gravity on the satellite. In this way the satellite manages to travel in an ellipse around the earth without additional propulsion.
You would see the satellite in the same direction all the time. The satellite is supposed to move around the Earth at the same speed as Earth's rotation.

The gravity is greater the nearer to Earth you go. The same is true for all planets.
it rotates around the Earth at the same rate and in the same direction as the Earth revolves on its axis so it is always fixed over the same point
A Geosynchronous or Geostationary satellite. The orbit period of a satellite will be longer the further it is away from the planet, so these have to be quite far away to match the rotation period of the earth. They orbit the earth once every 24 hours, so stay in the same apparent position when 'seen' from earth. This means that satellite dishes receiving signals from it can remain still, pointing in one direction rather than having to track it across the sky - a big advantage.
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.

Without gravity, the satellite will travel in the same direction it was going when gravity went to nil. This is due to the object's momentum, and the satellite will go off into space. And if the gravitation were nil to begin with, there would have been no orbit in the first place. The question is problematic, since planets will always have gravity. Picture a ball on a string that is being whirled around by someone. If the string snaps, the ball continues to move in the direction it was going at the moment the string snapped. It flies off in a tangent, and the satellite will do the same thing if gravity is suddenly reduced to zero.
