Two reasons to support the statement that artificial gravity can be produced when a manned satellite revolves around the Earth are:
Centripetal Force: When a satellite orbits the Earth, it experiences a centripetal force that acts towards the center of rotation. This force is required to keep the satellite in its circular path. The centrifugal force, which is an equal and opposite reaction to the centripetal force, acts away from the center of rotation. This centrifugal force creates a sensation of gravity for the occupants inside the satellite. As the satellite revolves, this centrifugal force acts as a substitute for gravity, effectively producing artificial gravity.
Consistent Acceleration: The occupants inside the revolving satellite experience a constant acceleration due to the circular motion. According to Einstein's equivalence principle, a constant acceleration is equivalent to the presence of gravity. Therefore, as the manned satellite revolves around the Earth, the occupants feel a consistent acceleration, which gives them the perception of gravity.
It is important to note that the strength of artificial gravity depends on the radius of the satellite's orbit and the rotational speed. By adjusting these factors, scientists can control the artificial gravity experienced by the occupants.
