ICP Buoyancy Quiz

Buoyancy is best described as:

• The force which allows that which would normally sink to float

• A force which pulls objects toward the center of the Earth

• Mass minus volume

• A lifeboat

The best example of buoyancy in action is:

• A Ship

• A Plane

• The Ocean

• Ocean volcanic vents

Density is a measure of how much matter is found in:

• A unit of time

• A unit of mass

• A unit of volume

• A unit of length

The formula for density is:

• mass/length

• mass/volume

• volume/mass

• 2(density - 1gram/cm^3)

How do you get a chunk of dense metal to float instead of sink?

• Nothing, all metals sink

• Add a less dense metal to the original metal

• Increase the volume of the metal by flattening its shape

• Compress the metal

Archimede's Principle is:

• Mass of the water is less than the force of buoyancy

• The weight of water displaced by the volume of a boat is equal to the force of buoyancy which pushes upward on the boat causing it to float.

• The volume of water which displaces the buoyancy causing the boat to float.

• Outdated by kings and crowns and therefore not used in science anymore

Who was Archimede's?

• 2020 Presidential candidate

• Scientist and mathematician who lived in 200BC

• Scientist who discovered gravity in Italy

• a ship captain

What is water displacement used to find?

• volume

• mass

• density

• weight

An object should float in a fluid if:

• it's more dense than the fluid

• it is 1kg in mass

• It's less dense than the liquid

• Has density of 1.0

What is volume?

• A measure of how heavy an object is

• The amount of matter in a body

• The space an object occupies

• The density of a fluid
