By placing satellites in orbit around the Earth, we are able to position them high enough so that they in position to relay messages from any location on Earth to any other location, and to observe weather patterns and observe and photograph virtually any detail on the surface, to give early warning of military activity, to enable the global positioning system which allows people on Earth to find out exactly where they are, and in some cases, to make useful astronomical observations, unimpeded by the Earth's atmosphere. Several other important uses are also possible, such as the proposal for solar power satellites, or the use of satellites to cut down on the sunlight reaching the Earth, as a solution to global warming.
A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
orbit
no, the moon is the Earths natural satellite, the moon is in orbit around the Earth. The whole Earth/Moon system is then in orbit around the sun.
A satellite is any object that is in orbit around another object. The moon is a natural satellite of the Earth because it orbits around the Earth.
Yes.

If a satellite is in an elliptical orbit around the Earth, the Earth will be at one of the focii. The speed of the satellite will then constantly be changing. It will move the fastest when it is nearest to the Earth (perigee) and slowest when it is furthest away (apogee).
A satellite, or the moon.
The time it takes for a satellite to complete one full orbit around the Earth, known as its orbital period, can vary depending on the altitude of the satellite. On average, a satellite in low Earth orbit (LEO) typically takes about 90 minutes to complete one orbit, while a geostationary satellite orbits the Earth every 24 hours.
A satellite's orbit is just the path it follows around the Earth or some other planet.Satellites' orbits can be elliptical or circular.
There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
