WHY ARTIFICIAL SATELLITE DOES NOT FALL REVOLVING ROUND THE PLANETS ?
Answers
So, How Do Satellites Stay in Orbit?
Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity. Satellites are sent into space by a rocket launched from the ground with enough energy (at least 25,039 mph!) to get outside our atmosphere. Once the rocket reaches its determined location it drops the satellite into its orbit. The initial speed of the satellite maintained as it detaches from the launch vehicle is enough to keep a satellite on orbit for hundreds of years.
A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull.
Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit. It is reserved for changing orbit or avoiding collision with debris.
The artificial satellites are set up in the atmosphere in such a way that the gravitational pull of the planet will keep it in one orbit and it's a perfect gravitational pull: neither too much to make it fall on the satellite, nor too less to allow the satellite to go away in space.
