8.3.B—Describe the buoyant force exerted on an object interacting with a fluid

Describe the buoyant force exerted on an object interacting with a fluid.

• The buoyant force is a net upward force exerted on an object by a fluid.
• The buoyant force exerted on an object by a fluid is a result of the collective forces exerted on the object by the particles making up the fluid.
• The magnitude of the buoyant force exerted on an object by a fluid is equivalent to the weight of the fluid displaced by the object. Relevant equation: TOPIC 8.3 Fluids and Newton’s Laws
