Why is weightlessness experienced while orbiting the earth in space ships? (1) Inertia (2) Acceleration (3) Zero gravity (4) None of these

1 Answer

Answer :

(4) None of these Explanation: The reason astronauts experience weightlessness which orbiting the earth in spaceships is that they are in free fall. A spacecraft in orbit is falling towards the Earth, because of gravity, but it is moving forward in its orbit fast enough that the path it follows is a curve that is a closed ellipse.
