Archimedes' principle

Archimedes' Principle states that... 

• The buoyant force acting on an object equals the volume of the fluid displaced by the object. 
• The buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object.
• The buoyant force acting on an object will always be equal. 

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

The upward force exerted by a liquid on an object immersed in or floating on the liquid

• pressure
• buoyant force
• normal force
• gravity

If an object is submerged in a fluid, the buoyant force acting on it is...

• Always greater than the weight of the object.

• Always equal to the weight of the object.

• Always less than the weight of the object.

How does Archimedes principle apply to the functioning of hot air balloons?

• he heated air inside the balloon is less dense than the surrounding air, causing the balloon to float due to the buoyant force.

• Archimedes principle does not apply to hot air balloons

• he balloon floats due to the weight of the hot air inside it

• The hot air inside the balloon is more dense than the surrounding air, causing the balloon to sink
