Bill Nye Buoyancy Video

When something does not sink or float, we say it is ___________buoyant

• Positively

• Negatively

• Neutrally

• Floaty

If two objects are made of the same substance and have the same mass, the shape of the object determines whether or not it sinks or floats in a fluid.

• True

• False

If an object floats in water, the weight of the water displaced is greater than the weight of the body immersed in water. 

• true

• false

If you put a brick in a tub filled to the top with water, the amount of water that overflows is equal to the volume of the brick.

• true

• false

What is buoyancy?

• The ability of an object to float in a fluid

• The weight of an object in air

• The density of a fluid

• The temperature of a fluid

Which principle explains why ships float?

• Pascal's Principle

• Archimedes' Principle

• Bernoulli's Principle

• Newton's Third Law

What happens to the buoyant force as an object is submerged deeper in a fluid?

• It increases

• It decreases

• It remains the same

• It becomes zero

If an object is less dense than the fluid it is in, it will:

• Sink

• Float

• Stay suspended

• Dissolve

What is the unit of density?

• Kilogram

• Newton

• Pascal

• Kilogram per cubic meter

Which of the following objects will float in water?

• A metal coin
