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.
