Buoyancy and Floating Quiz

What is the principle called that states that the buoyant force on an object is equal to the weight of the fluid it displaces?

• Pascal's Principle

• Archimedes' Principle

• Newton's Law

• Hooke's Law

If an object floats on water, what can be said about its density compared to the density of water?

• It is greater than the density of water

• It is less than the density of water

• It is equal to the density of water

• Density is not related to floating

When an object that floats is placed in a full container of water, the water level (a)   .

• The water level goes down
• The water level stays the same
• The water level goes up
• The water level first goes up, then

• Gravitational force

• Buoyant force

• Magnetic force

• Water resistance

Why did the Titanic sink after hitting an iceberg?

• The iceberg had a greater density than the Titanic

• The buoyant force on the Titanic decreased

• The Titanic's density became greater than the water

• The iceberg pushed the Titanic out of the water

What is the term used to describe the amount of mass per unit volume of a substance?

• Weight

• Volume

• Density

• Mass

What must be true for an object to float in a fluid?

• The object's mass must be less than the fluid's mass

• The object's density must be equal to the fluid's density

• The object's density must be less than the fluid's density

• The object must be completely submerged

Water displacement helps to determine (a)   about an object.

• The color of the object
• The density of the object
• The smell of the object
• The sound of the object

Which of the following would likely sink in water?

• A balloon filled with helium

• A wooden block

• A metal spoon

• A plastic foam ball

What is the effect of buoyancy on a submerged object?

• It increases the object's weight

• It decreases the object's weight

• It has no effect on the object's weight

• It makes the object's weight fluctuate
