Question

when a satellite revolves close to the surface of the earth orbital velocity becomes​

Answer 1

Answer:

Gravity pulls an orbiting object towards the center of the planet and also provides the acceleration that forces the object to travel in a circular path. The result being, that an object with a certain velocity will achieve stability when it is at a distance from the center of the planet where the equations balance.

Force of gravity equals the centripetal force.

Explanation:

So, orbital velocity (for a circular orbit) is:

Escape velocity is the velocity at which an object can overpower gravity, without additional force (e.g. thrusters). The concept called escape velocity determines how fast an unpropelled object will travel with gravity as its decelerant. The idea being that the object will continually slow but gravity will continually weaken as the object gets farther away. At escape velocity, the speed will hit zero at distance infinity.
