There are two reasons to support the statement that artificial gravity can be produced when a manned satellite revolves around the Earth:
Centrifugal Force: When a manned satellite revolves around the Earth, it experiences a centripetal acceleration directed towards the center of the orbit. According to Newton's laws of motion, an object undergoing acceleration experiences an outward force known as the centrifugal force. This centrifugal force creates a sensation of gravity-like acceleration towards the outer rim of the satellite. As a result, the occupants of the satellite would experience a force pushing them towards the floor, simulating the effects of gravity.
Equivalence Principle: The Equivalence Principle is a fundamental concept in general relativity that states that the effects of gravity are equivalent to the effects of acceleration. In the case of a manned satellite revolving around the Earth, the occupants of the satellite are constantly accelerated due to the satellite's circular motion. From the perspective of the occupants, this acceleration is indistinguishable from the force of gravity. Therefore, they would feel as though they are in a gravitational field, similar to the gravity experienced on the surface of the Earth.
By utilizing the centrifugal force and the equivalence principle, a manned satellite can generate an artificial gravity-like environment for its occupants, allowing them to experience the sensation of gravity even in space. This concept has been explored in science fiction and has also been considered in the design of certain space habitats or spacecraft proposals.
