How does satellites work

 Hello Dear viewers Lets get start todays Article We live our lives knowing that many satellites orbitour planet every day, and that they are helping us in several ways. You might be surprised to know that there are almost 4900 satellites orbiting the Earth. The most obvious questions that come to mind are, why are these satellites in totally different orbits? How does the satellite carryout all of its functions? And what are the components inside them, which help them to accomplish all of their allotted tasks? Let's explore the answers toall these questions in detail. It's a well known fact thata satellite stays in orbit because of the balance between gravitational pull and centrifugal force. The angular velocity of the satellite is decided by the force balance equation that balances the gravitational and centrifugal forces. When the satellite is deployed, it is given sufficient speed to balance these two forces. A satellite near to Earth requires more speed to resist the grav...
