Answer to Question 1

A satellite is put into orbit by accelerating it to a sufficiently high tangential speed with the use of rockets. If the speed is too high, the spacecraft will not be confined by the Earth's gravity and will escape, never to return. If the speed is too low, it will return to Earth. If the satellite stopped moving, it would fall directly to Earth.
