Buoyant force definition for kids
WebFrom Academic Kids. In physics, buoyancy is an upward force on an object immersed in a fluid (i.e. a liquid or a gas ), enabling it to float or at least to appear to become lighter. If the buoyancy exceeds the weight, then the object floats; if the weight exceeds the buoyancy, the object sinks. If the buoyancy equals the weight, the body has ...
