Buoyancy happens across the universe on scales small and great. From ice cubes to icebergs, from hot air balloons to some of the largest bubbles in the universe, blown by giant black holes into ...

The film discusses the evolution of navigation and the principles of buoyancy, stability, and propulsion in watercraft. It explains how objects float based on the displacement of water and the ...

Since the buoyancy force is due to the interaction between the object and the water surrounding it, this rock will have the same buoyancy as the cube of water.

I think my best explanation of buoyancy was in the post about MythBusters floating a lead balloon. But, basically for buoyancy there is an upward force from the water on the thing that is floating.
