Which force pushes occupants toward the outer walls of a spinning spaceship?
Answer
Centrifugal force.
When a spacecraft or space station is set into rotation, the inertia of the objects inside causes them to resist the circular motion and push outward against the structure of the vessel. This outward push is referred to as centrifugal force. By shaping the interior of the vessel so the floor is positioned against the outer wall, this force acts as a substitute for weight, pulling occupants toward the floor and providing a sensation of artificial gravity.
