1.	The objects which are thrown upwards from the earth and return back to earth whereas artificial satellite does not return back. Why?
Answer» Due to earth’s gravitational force all the objects thrown up come down while an artificial satellite do not because it is launched more than the speed of gravitational force i.e. 4.2 km/sec. So it crosses the gravitational force of the earth and move around the earth in fixed orbit.
