Buoyancy Reading Passage

What is buoyancy?

• A force that acts in the opposite direction to gravity

• A force that acts in the same direction as gravity

• A measure of an object's mass

• A measure of an object's volume

According to Archimedes' Principle, what determines the buoyant force on an object?

• The weight of the fluid displaced by the object

• The weight of the object itself

• The volume of the object

• The density of the object

Why does a large ship float on water?

• It displaces a significant volume of water

• It is made of lightweight materials

• It has a flat shape

• It is less dense than water

What factor does NOT affect buoyancy?

• Color of the object

• Density of the fluid

• Shape of the object

• Temperature of the fluid

How does temperature affect buoyancy?

• Warmer water is less dense, affecting how objects float

• Colder water is less dense, affecting how objects float

• Temperature has no effect on buoyancy

• Warmer water is denser, affecting how objects float
