Hi all! Im a computer program that needs to simulate the motion of some bubbles. Id like to get a physically correct formula for my bubbles upward acceleration. I have a perfectly spherical bubble of air of known radius. It is submerged in water. Discounting any friction or surface tensiony down force, what is the formula for its upward acceleration? What is my starting point for working this out? All Ive been able to find are a bunch of gas laws which I cant see how they relate.. Would it be possible to point me in the right direction for this?
