What is the upward push of a liquid on an object?

• Volume

• Displaced water

• Density

An object will _____if the mass of the object is equal to the mass of the water displaced upthrust.

• float

• sink

• either float or sink

This is what happens to an object when the gravitational force is stronger than the buoyant force.

• sinks

• floats

• neutrally buyant

• I don't know...

An object will _____if the mass of the object is greater than the mass of the water displaced upthrust

The ship was able to float in the water because its weight was the same as the weight of the water it displaced.

• True
• False

If we place an empty sealed plastic bottle in water, we know it will float. What could we do to make it sink?

• You can't make a plastic bottle sink

• Increase mass (fill it with coins)

• Fill the bottle with helium

• Decrease mass (use a bottle made out of lighter plastic)
