Feeling of weightlessness in a satellite is due to

An astronaut experiences weightlessness in a space satellite It is because .

Explain the reason of weightlessness inside a satellite.

intelsat satellite is used for:

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.

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.

Why do bodies become weightless in artificial satellites ?

As the earth rotates about its axis, a person living in his house at the equator goes in a circular orbit of radius equal to the radius of the earth. Why does he/she not feel weightless as a satellite passenger does?
