1 Answer

Answer :

A satellite that is sent into space and keeps moving. That is, once it is in motion, it will remain in motion for life and will never stop. So as not to fall down. If an object, not just a satellite, is sent at that speed, it will be moving for life. The velocity is afraid of the gravitational formula from time to time and from the surface to the height. Centrifugal force = mv * 2 / R + h and gravitational force = GMm / (r + h) * 2. Mv * 2 / R + h = GMn / (R + h) * 2 or , v * 2 = GM / R + h and the duration of the artificial planet , T = 2 * 3.14 \ / "" (R + h) * 3 / GM is working on a theory of release speed and space is possible.
