Which term describes the upward buoyant force acting on a body that displaces water?

Which term describes the upward buoyant force acting on a body that displaces water?

• A. ARCHIMEDES PRINCIPLE
• B. BUOYANCY
• C. GRAVITY
• D. LIFTING FORCE

Answer: (B)

Buoyancy is the upward force that a fluid exerts on a body as it displaces water. This force arises because water pressure increases with depth, creating a net push upward on any portion of the body that is in contact with the fluid. The size of this buoyant force is related to the amount of water the body displaces—the heavier the water displaced, the stronger the buoyant push. Archimedes' principle explains why buoyancy exists and how to calculate its magnitude (the buoyant force equals the weight of the displaced water), but the term that names the upward force itself is buoyancy. Gravity is the downward pull on the object, and lifting force is a more general term that doesn’t specify the fluid context. In boating terms, buoyancy is what helps a hull float by providing that upward lift proportional to the displaced water.
