What is buoyant force?

• An upward force exerted by fluids on an object.
• An downward force exerted by fluids on an object.

What is displacement?

• The ability to float

• Degree of compactness of a substance

• The moving of something from its place or position

Who was the first person to connect displacement of water with buoyancy?

• Mr. Müller

• Plato

• Archimedes
