State two difference between the artifical satellite of the Earth and its natural satellite Moon.

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.

A man inside an artificial satellite feels weightlessness because the force of attraction due to earth on him is

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.
