How constant acceleration affects the tripulation of a spaceship?

Click For Summary

Discussion Overview

The discussion revolves around the effects of constant acceleration on the crew of a spacecraft, particularly in the context of interstellar travel. Participants explore whether individuals aboard a spacecraft accelerating at 1g would experience a sensation similar to gravity or if they would be weightless.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether the crew would feel weightless or experience a force pushing them towards the back of the ship during constant acceleration at 1g.
  • Another participant asserts that the crew would not be weightless and would feel a force equivalent to 1g, pushing them into the back of the ship.
  • A third participant references Einstein's equivalence principle, stating that constant acceleration is indistinguishable from gravity, suggesting that passengers would feel as if the ship were on Earth.
  • There is a clarification regarding the term "tripulation," with participants noting it likely refers to the crew, and acknowledging the OP's language background.
  • The OP expresses gratitude for the responses and indicates a newfound understanding of the implications of acceleration on human tolerance during long space journeys.

Areas of Agreement / Disagreement

Participants generally agree that constant acceleration at 1g would create a sensation similar to gravity for the crew. However, there is some ambiguity regarding the terminology used and the implications of acceleration limits on human tolerance.

Contextual Notes

Some participants note the OP's language background, which may have influenced the initial phrasing of the question. There is also an acknowledgment of the potential limitations on acceleration tolerable by humans during long-duration space travel.

Who May Find This Useful

This discussion may be useful for individuals interested in space travel, the effects of acceleration on human physiology, and the principles of relativity as they relate to space exploration.

I appologize for any spelling or grammar errors. Please take into account that English isn't my first language and that I haven't finished my English course yet, since I'm 14 years old.

My Question (which I suppose is very dumb): Imagine there is a manned spacecraft traveling through deep space accelerating at a constant rate of 1g (10 m/s²). Would the tripulation feel a constant pull towards the back of the ship equivalent to gravity on Earth? Or would they float weightlessly? Why?

I'm thinking about interstellar travel and I thought that maybe accelerating beyond 1g would be harmful, because the tripulation would experience a strong gravity-like force pulling them towards one end of the ship (the back end, in case the vehicle was accelerating, or the front end, in case it was decelerating).

The answer and the explanation are probably very obvious, so thanks in advance for anyone taking their time to answer this.

I don't know what "tripulation" means, and a search of the dictionary turned up nothing. However, I assume you are asking whether passengers, whether people or objects, would be weightless or not. The answer is that they would not be weightless. They would be pushed into the back of the ship with an acceleration of about 9.8 m/s2, or 1g.
 
About one hundred years ago Einstein formulated his "equivalence principle". It states that gravity is the same as constant acceleration. So in a ship accelerating at 1 g toward its front, its passengers and objects would feel gravity as if the ship were standing on the Earth its front pointing upward.

S(he) meant to say the crew of the ship. The OP's first language is probably either Spanish or Portuguese. The word for crew in Spanish, for instance, is tripulación. In Portuguese it is tripulação.

That's exactly what I meant. My first language is indeed Portuguese.

Thank you all for your answers, the subject is now clear to me. In long manned space trips to distant stars, we are then not only limited in terms of highest speed achievable but also in the highest acceleration tolerable by the human crew.
 
I like the way you rationalize kid! keep thinking
