1)      The buoyant force of an object is dependent on the____________________ of the object that is underwater.

• weight

• mass

• volume

• density

What happens to the buoyant force on an object as it is lowered or forced into the water?

• it increases

• it decreases

• It goes to zero

• it remains the same

1)      The buoyant force on an object is equal to the _________________________ of the water it displaces.

• mass

• weight

• volume

• density

A steel boat floats on water.  How can a steel boat float when a cube of steel will sink in water?

• The steel in the boat is less dense.

• The average density of the boat is less than water.

• The average density of the boat is greater than water.

• The average density of the boat is the same as water.
