Buoyancy is the upward force of a fluid that opposes the weight of an object in it. Learn about Archimedes' principle, the formula for buoyancy, and how buoyancy affects objects and fluids in different situations.
Archimedes' principle allows the buoyancy of any floating object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight. The upward, or buoyant, force on the object is that stated by Archimedes' principle above.
16 wrz 2024 · Archimedes’ principle, physical law of buoyancy stating that any body submerged in fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body. Learn more in this article.

Archimedes’ principle states that the buoyant force on the object equals the weight of the fluid displaced. This, in turn, means that the object appears to weigh less when submerged; we call this measurement the object’s apparent weight .
Archimedes principle: The buoyant force on the ship (a) is equal to the weight of the water displaced by the ship—shown as the dashed region in (b). The principle can be stated as a formula: \[\mathrm{F_B=w_{fl}}\]
