Despite what you see in science fiction movies, we don't know howto make artificial gravity. However, we can make something thatseems like gravity if we work in a rotating reference frame.Suppose NASA builds a space station as a 1000-m-diameter cylinderthat rotates about its axis. The inside surface is the deck of thespace station, so that people stand on the inside surface of thecylinder. As they move on the rotating cylinder, its floor willpush against their feet providing the centripetal force they needto move in a circle.What rotation period will provide "normal" gravity?
