If a satellite slows down, it will start to move closer to Earth as gravity becomes more dominant. This can lead to its orbit decaying and potentially reentering the Earth's atmosphere. Additionally, a slowdown could affect the satellite's ability to maintain its position for communication or observation purposes.
Because it's in the orbit of Earth. It's in the orbit of Earth because of gravity +++ Confused. A satellite is travelling at high speed (even if in geostationary orbit) so its inertia keeps it "up" by "centrifugal" force. If it slows it will start to return to Earth.
Atmospheric drag can cause a satellite in orbit to lose altitude and eventually re-enter Earth's atmosphere. As the satellite moves through the atmosphere, it experiences friction which slows it down and reduces its orbital velocity. Over time, this can lead to a decay in the satellite's orbit, causing it to re-enter the atmosphere.
If the speed of a satelite orbiting earth were to decrease, it's orbit would come closer to the earth, and eventually it would fall to the Earth. Space administratioins(like NASA) use calculus and whatever fancy term thay use for their math to try and make it land in a safe place. On the other hand, if it were to increase in speed, it would eventually leave Earth's orbit.

Orbits within the atmosphere are not stable due to atmospheric friction. Friction slows (and heats) the satellite, dropping its orbit still lower (where there's more friction, therefore more slowing and heating). Eventually the satellite burns up. This is essentially what happened to Skylab and more recently to Mir.

Basically, a moon does not need energy to keep it in orbit.Initially it does need energy to give it some velocity to set up the orbit.A natural satellite is often an object that has been captured from a solar orbit. In that case the kinetic energy is already there in the object's orbit around the Sun. Earth's natural satellite, the Moon, was the result of a collision between Earth and another planet.The initial kinetic energy of the Moon still came out of the movements of the colliding planets.Actually, as a result of tidal forces, some energy isslowly being transferred to the Moon from Earth's rotation. The Moon is slowly drifting into a higher orbit as Earth's rotation slows. This has been going on since the Moon's formation over 4.5 billion years ago.
