How constant acceleration affects the tripulation of a spaceship?

AI Thread Summary
In a spacecraft accelerating at a constant rate of 1g (10 m/s²), the crew would experience a force pushing them towards the back of the ship, similar to the feeling of gravity on Earth. This phenomenon is explained by Einstein's equivalence principle, which states that constant acceleration is indistinguishable from gravitational force. The crew would not float weightlessly; instead, they would feel a gravitational pull equivalent to that on Earth. Additionally, the discussion highlights that during long space missions, both maximum speed and tolerable acceleration are critical factors for human comfort and safety. Overall, understanding these dynamics is essential for planning interstellar travel.

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
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds?

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
