A person in an artificial satellite of earth feels weightlessness. But a person on the moon has weight eventhough moon is also a satellite . Why ?

A person in an artificial satellite of Earth feels weightlessness. But a person on the Moon has weight though the Moon is also a satellite of the Earth. Why?

Statement-1: The plane of the orbit of an artificial satellite must contain the centre of the Earth. Statement-2: For an artificial satellite, the necessary centripetal force is provided by gravity.

Assertion: A person sitting in an artificial satellite revolving around the earth feels weightless. Reason: There is no gravitational force on the satellite.

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.

Assertion : The gravitational attraction of moon is much less than that of earth. Reason : Moon is the neutral satellite of the earth.

Assertion : On satellites we feel weightlessness. Moon is also a satellite of earth. But we do not feel weightlessness on moon. Reason : Mass of moon is considerable.

STATEMENT -1 : Weightlessness is observed in an artifical satellite and this weightlessness does not depend upon the height of satellite above Earth's surface. and STATEMENT -2 : Weightlessness is not observed upon moon because mass of moon is much larger than that of artificial satellite. The weight of a body upon moon is due to the gravitational pull of moon upon the body.

Statement-1: Moon cannot be used as a satellite for communication. Statement-2: Moon doesn't move in the equatorial plane of the earth.
