- TL;DR Summary
- Jupiter g ~ 25 Would you feel it?
I know that in Earth, an astronaut feels weightless in orbit but actually is not. The astronaut would not feel his own weight until he actually stands on a floor where his feet point towards the Earth as the Normal Force is the perception of weight.
So, in Jupiter, where g ~ 25, an astronaut in freefall also would not feel their own weight. However, does that mean there would be no biological effects despite the increased gravity?
I have heard it said that a person who normally has a weight of 600 Newtons on Earth would then weigh ~ 1500 Newtons on Jupiter, enough to have a heart attack since a normal heart could not pump blood through such excess weight. But if the person is in freefall in Jupiter, this would not happen as they would need to have their feet on the surface of a ship to feel this 1500 Newton. Is this correct?
Please ignore everything else about Jupiter except for what is the discussion here. I am well aware of all the problems of falling into Jupiter, just had a question of this one detail.
