Archimedes, Bernoulli's & Pascal Principle

Bernoulli’s principle states that the pressure in a fluid decreases as its velocity increases. 

• True
• False

When air is moving quicker it's pressure is greater.

• True
• False

Archimedes Principle states that the buoyant force acting on a submerged object is equal to the density of the fluid displaced by the object.

• True
• False

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

• true
• false

What is the volume of Object X?

• 10.0 cm³
• 15.0 cm³
• 20.0 cm³
• 25.0 cm³

What direction is the buoyant force in?

• Downward
• Left
• Right
• Upward

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. 

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

• Sink
• Float 
• Expand
• Shrink

This principle states that the faster a fluid moves, the less pressure the fluid exerts.
