Cách sử dụng
Buoyancy is a term that describes how things float or stay afloat in a liquid, like water. It can also be used to refer to the ability of an object to rise or float in air. For example, a balloon is buoyant in air because it has air inside that is lighter than the surrounding atmosphere. In water, an object will be buoyant if it is less dense than the water it displaces. Buoyancy is important in swimming, scuba diving, and shipbuilding, among other areas.
