Archimedes Principal

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
