I was wondering why things float (leading up to buoyancy) from a physics point of view. My viewpoint is that something floats when it is less dense than water. But i was wondering how floating is explained from a forces point of view.
I have looked at Archimedes principle and this says 'Any floating object displaces its own weight of fluid.' I was not aware that floating objects displaced any fluid. I naively thought a floating object simply sat on top of the liquid. I do have more questions but I may as well wait until someone clears that misconception up for me :)
