MFE - Floating and Sinking

Archimedes' Principal says that the buoyant force of an object is equal to

• the weight of the fluid it is in/on.

• the mass of the fluid it is in/on.

• the weight of the fluid it displaces.

• the volume of the fluid it displaces.

Buoyancy is the ability to

• float.

• sink.

• be submerged.

• be wet.

Buoyant force acts in the _________ direction of gravity so objects feel lighter.

• same

• opposite

Density is the amount of

• temperature of a given object.

• momentum in a given volume.

• mass in a given object.

• mass in a given volume. (SI units only!)

The density of water is

• 1 g/cm³

• 1 g/m²

• 1 kg/cm²

• 1 g/in²

Mass is the measure of ____________ in an object.

• speed

• acceleration

• matter

• density

Solids, liquids, gases, and plasma are all of the forms of

• density.

• mass.

• matter.

Negative buoyancy results in an object

• floating.

• sinking.

• being wet.

Neutral buoyancy results in an object

• floating.

• sinking.

• being wet.

• being suspended. (neither sinking nor floating)

Positive buoyancy results in an object

• floating.

• sinking.

• being suspended.
