Here's a weird, theoretical question that I couldn't quite decide the answer to by myself. Let's say you have a guy standing on a planetoid of some sort. The planetoid has the same gravity at its surface as Earth does: 1g (just for simplicity). Now, if this planetoid accelerates directly away from the person (i.e. in the direction they'd fall if the ground gave out) at 1g itself, would the gravity of the planet cancel out the feeling of acceleration for our guy? Would he be weightless as he's dragged along by the planet's gravity, constantly falling toward it as long as the rate of acceleration and everything else remain perfect? I have a feeling I might be missing other factors, and I'm also not sure how Newton's third law would factor in here. Thanks for any thoughts.
