Artificial satellites are outside of the atmosphere, and therefore do not experience any friction with it. They are in the vacuum of space, where nothing will slow them down by friction. Since they have enough velocity to keep from dropping below the atmosphere of Earth, they are in a stable orbit, the same way the Moon is. However, they do not move at perfectly uniform speed. Like all satellites of all bodies, they move more speedily when they are closer to earth and less speedily when they are farther away from Earth. Their orbits can be corrected by changing their orbital velocity, but it is nearly impossible to get a perfectly circular orbit. Being in a close to circular orbit, they remain nearly uniform in velocity.
There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
It would need to be launched into a tangent plane parellel to that of the earth's orbit around the sun, with the same speed of rotation around the sun
it's hot. ;)
The polar orbit so that it can measure cold and hot points around the entire earth :)
It has to get up to 7km a second to get out of earth's orbit, then it orbits around earth.
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.
