If you don't like the movements, sit near the wing, you will feel less pitching and rolling there.
If you like to know what is going on, sit in a window seat and watch the movements.
My wife is a terrible flyer, she tried to get off a plane once at 30,000 feet because she didn't like the bumps ! She likes to sit near the air stewards/stewardesses and watch them, her theory being that they fly every day so she has no need to panic unless they do !
