Science Buddies: "Ask an Expert"

So if i had a spaceship and it could go anywhere really fast but not too fast as i realise that if you go to accelerate to fast then you die. Anyway my question is that if i am in space with no gravity acting on me i will experience no weight but as soon as my spaceship start moving i move as well in the opposite direction to the spaceship. When i reach the wall of my spaceship it pushes against me and i move along with teh spaceship. If i have a circle ship that moves up so that the gravity made when accelerating will push me down on the floor how would i work out what the gravity is so that i can go faster without someone else dying?
How do i work out the gravity in a spaceship when accelerating?
