Figure 5.18 shows a space station rotating about an axis. Because of the rotational motion, any object located at a point P on the interior surface of the station experiences a centripetal force directed toward the axis. The surface of the station provides this force by pushing on the feet of an astronaut, for instance.
In Figure 5.18, what kind of force is actually making the astronaut feel "artificial gravity"?
A normal force
A gravitational force
A tension force
There is no actual force acting on the astronaut, it just feels that way.
The Attempt at a Solution
The physiological effects of prolonged apparent weightlessness are only partially known.
To minimize such effects, it is likely that artificial gravity will be provided in large space stations of the future.
