Archimedes Principle

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

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

• Sink
• Float 
• Expand
• Shrink

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. 

What direction is the buoyant force in?

• Downward
• Left
• Right
• Upward

What causes the apparent weight loss of an object immersed in water?

• Gravity
• Buoyancy
• Newton's 1st law
• Newton's 2nd law

Buoyancy force equals

• weight of displaced water
• the "weight loss" of the object immersed in water
• upward force of water 
• all of these 

The buoyant force on an object equals 250 N. What is the weight of the displaced water?

• 250 N
• 250 lbs
• 250 N/9.8 m/sec²
• not enough information given

What direction is the buoyant force in?

• Downward
• Left
• Right
• Upward

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
