Artificial Gravity: What Makes Objects Press Towards Rotating Satellites?

Click For Summary
SUMMARY

The phenomenon of artificial gravity in rotating satellites is primarily caused by centripetal forces acting on objects within the satellite. As the satellite spins, the outer rim exerts a force that keeps objects in a circular path, mimicking the sensation of gravity experienced on Earth. If the satellite's wall were removed, objects would continue in a straight line due to inertia. The effects of acceleration towards the center of rotation can be perceived as gravitational force, provided the object is small relative to the satellite's radius and remains stationary.

PREREQUISITES
  • Centripetal and centrifugal forces

When an object is present in a rotating satellite it is pressed towards the rim of satellite.What in the world makes it press?

centripetal/centrifugal forces. Do a quick google of artificial gravity, there will be lots of info.
 
The outside rim of the satellite is constantly pushing at the object to keep it in its circular path. If you took the wall away, the object would just keep on in a straight line. The sensation of the outside rim pushing on you (the object) is precisely the same as the sensation of the ground pushing up at you when you are standing on Earth.

Acceleration towards the centre of rotation is indistinguishable from a gravitational force as long as
1. The object is small compared with the radius of the spinning ship and,
2. you don't try to move about. If you go to touch your toes, you could fall over because of an effect knows as Coriolis Force.
