Science Buoyancy Archimedes

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

• pressure
• buoyant force
• normal force
• gravity

The buoyant force on floating objects equals the weight of the floating object 

• true
• false

If an object weighing 50.0 N displaces a volume of water with a weight of 10.0 N, what is the buoyant force on the object?

• 10 N
• 60 N
• 40 N 
• 20 N 

Which bundle weights more?

• 1 kg of nails
• 1 kg of cotton
• both have the same weight

The volume of the liquid an object displaces will be equal to the buoyant force. 

• True
• False

When the weight of an object is greater than the buoyant force, the object will ... 

• Sink
• Float 
• Expand
• Shrink

If an object is more dense than the fluid which it is in, the buoyant force will be less and the object will ... 

• float
• sink
• shrink
• expand

If the mass of an object is 6kg on earth.  what would the mass be on the moon?

• 6kg
• 0kg
• 1kg
• 13kg
