Okay, this is a little complicated and my understanding of physics is rather shaky so please bear with me. Basically, one of my stories is set on a spaceship that has a rotating section to generate gravity. It has it because it's a really long trip, muscle atrophy is something that they really want to avoid, and the alternative means of generating an approximation of gravity in a reasonably hard sci-fi setting, acceleration, isn't feasible due to continual acceleration not being a viable option since as I said above it's a really long trip. Problem is that they still need to accelerate at the start of the journey to get up to cruising speed and decelerate at the end of it, which would result in two sets of g-forces going in different directions. How do I go about minimizing the problems that this may cause for those inside the ship? At the moment my leading idea is to have the ship accelerate/deceleration at a rate that generates fewer Gs than the rotating section so that there's always a dominant direction for "down" but I'm unsure if that would work and even more unsure how big the difference would need to be.
