While orbiting around the earth in a spaceship, an astronaut experiences

Why does an astronaut experience weightlessness in outer space?

Discuss the weightlessness experienced by an astronaut in an orbiting satellite.

The astronauts in a satellite orbiting the Earth feel weightlessness. Does the weightlessness depend upon the distance of the satellite from the Earth ? If so how ? Explain your answer.

Assertion : An astronaut in an orbiting space station above the earth experience weightlessness. Reason : An object moving around the earth under the infuence of earth's gravitational force is in a state of 'free fall'

Assertion : On earth's satellite, we feel weightlessness. Moon is also satellite of earth. But on the surface on moon, we do not feel weightlessness Reason : Gravitational force by earth on us on the surface of moon is zero. But gravitational force by moon on us on its surface is non-zero.
