Hello. I'm currently looking for a formula that would determine the G forces that a spaceship (and the people in it) would suffer whilst in it's travels. The current formula being used takes acceleration of the ship into account, but not a planet's. Therefore, even though i'm supposed to be in a freefall, the formula says I'm experiencing XX G's, even though I shouldn't be. I'm just not smart enough to figure this out. can anyone help me please?
