Question

Why satellites revolve rather than staying still in space?

Answer 1

some satellites are geostationary but some revolve around earth . because some satellites are send in space to keep a watch on a particular area but as the earth rotates it's impossible for a satellite to be in a place and keep a watch on it. hence the satellites revolve

Answer 2

⭐ There are two important forces acting on the satellite :-

✔ The gravitational force which will pull the satellite towards earth and

✔ The centrifugal force (due to revolution) which counters the gravitational pull.
