SUMMARY

The discussion centers on the effects of spinning in a vacuum, specifically at high rotational speeds such as 500 RPM. Participants confirm that even without external reference points, a person would experience G-forces due to the non-inertial nature of rotational frames. The physics of blood flow is examined, highlighting how centrifugal forces affect blood molecules in the body, particularly in the extremities. The conversation concludes that one would indeed feel the effects of spinning, even at a constant rotational velocity.

PREREQUISITES
  • Understanding of non-inertial reference frames
  • Basic knowledge of centrifugal force
  • Familiarity with human physiology, particularly blood circulation
  • Concept of rotational motion dynamics
NEXT STEPS
  • Research the effects of centrifugal force on human physiology
  • Explore the principles of rotational motion in physics
  • Learn about non-inertial reference frames and their implications
  • Investigate the mathematical modeling of blood flow under varying forces
USEFUL FOR

Physicists, students of mechanics, medical professionals interested in circulatory dynamics, and anyone curious about the effects of rotation on the human body.

You are the only object in space. Nothing else:

If you spin around really really fast, like 500rpm or whatever, would you be able to tell that you were in fact spinning around your self? There's no ebjects around you to relate to. But would you feel a G force, like with blood rushing to your head?

Rotational frames are non-inertial, so yes, you don't need any reference frame other than yours to tell that you are spinning.
 
yes, consider a blood molecule in your foot, as you spin it wants to maintain its velocity and go straight tangetial to the circle , but the normal force of the wall of your vein keeps it spinning. but a blood molecule in your knees would be forced to your feet until it found a contact force to keep it spinning,

this sounds fun I might decide to be irresponsile and waste some time figuring out what rpm would be needed for blood not to be pushed in from your extremities.

ok that's a hell of a problem, no time, but yes I believe youd feel it even at constant rotational velocity
