Is there a difference in submerged objects and floating objects? I know in floating objects that the Force of Buoyancy has to equal the Force of the object, but I'm not sure about submerged objects. What exactly is a submerged object? Another question I have: what exactly does volume have to do with buoyancy? Lastly: I was given three equations and I wanted to know when and how I used them: Fnet = pVdisplacementg Fnet = mg-pVg mg = pVg (or m=pV) All help is appreciated and sorry if these questions seem rather like 'duh' questions, but I simply don't understand buoyancy and I don't want to fall behind in class.
