What are the two factors that determine whether an object is buoyant?

• Amount of water it displaces and its density

• Amount of air it displaces and its density

According to Archimedes' principle, the buoyant force acting on an object is equal to the weight of the fluid displaced by the object. True or False?

• False

• True

What is the net upward buoyancy force equal to?

• Weight of the fluid displaced by the object

• Density of the object

What is the result of the pressure difference between the top and bottom of an object submerged in a fluid?

• Buoyancy

• Friction

What is the upward force exerted by a fluid on an object submerged or floating in it called?

• Buoyancy

• Traction

What does buoyancy enable the object to do?

• Sink

• Float

What is the origin of the word 'buoyancy'?

• French

• Spanish

What is the buoyancy force on an object making it rise or move upward?

• Gravity

• Buoyancy

What is the force that makes things lighter in water and stops them from sinking straight down?

• Tension

• Buoyancy

What are the two things that affect how much buoyancy an object gets?

• Amount of water it pushes away and its weight

• Amount of water it displaces and its density
