Explanation:
Detailed explanation-1: -The two forces acting on the rocket immediately after leaving the launching pad are gravitational force and frictional force. The gravitational force acts downwards towards the earth and frictional force acts due to surrounding air. Was this answer helpful?
Detailed explanation-2: -Newton worked out that, if the distance from the centre of the Earth doubles, gravity becomes a quarter as much as it was on the surface. A satellite with a mass of 1, 000 kg has a weight force of 9, 800 N at the Earth’s surface.
