Buoyant

What is buoyant force?

• An downward force exerted by fluids on an object.

• An upward force exerted by fluids on an object.

If an object is nuetrally buoyant it will________.

• Sink

• Float

• Neither float or sink

• Objects cannot be nuetrally buoyant.

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

• Sinks

• Neutrally Buoyant

• Floats

• I don't know...

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

• Sinks

• Neutrally Buoyant

• I don't know...

• Floats

What is it called when an object when the buoyant force is EQUAL to the the gravitational force.

• Sinks

• Neutrally Buoyant

• Floats

• Sinks really fast

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

• Increase mass (fill it with coins)

• Fill the bottle with helium

• You can't make a plastic bottle sink

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

An object that floats has

• Negative Buoyancy

• Positive Buoyancy

Which properties affect buoyancy?

• Colour

• Mass

• Density

• The place BOYancy was born

If the liquid the object is placed in is less dense than the object, the object will...

• Sink

• Float

• All of the Above

• Change Colour

Which box has a higher density?

• It is impossible to tell

• Box A

• Box B

• They are equal.
