Archimedes' Principle states that

• Buoyant force is equal to the mass of fluid displaced by an object.

• Buoyant force is equal to the weight of the fluid displaced by an object.

What determines if an object will sink or float?

• There is not enough information

• The buoyant force compared to the weight of an object

• The buoyant force compared to the volume of an object

Which of the following is dependent on gravity?

• mass

• weight

Buoyancy is the

• upward force of a fluid

• weight of an object

• downward force of a fluid

If the density of an object is greater than the density of water, it will

• sink

• float

• fly

If the density of an object is less than the density of water, it will

• float

• sink

The formula to find average density is

• D= m/v

• D=v/m

• D=m X V

The density of water is

• 1 g/ml

• 10 g/ml

How do steel ships float, even though steel is denser than water?

• Boats are not made of steel

• Boats can only float in salt water

• The density of the steel is reduced by hollowing out the boat to increase its volume.
