Buoyancy

Question 1

What is the archimedes principle?

Answer 1

• an object completely or partially immersed in fluid is “buoyed up” by force equal to weight of the fluid displaced

Question 2

What is neutral buoyancy?

Answer 2

• object displaces volume of water equal to weight
• maintain position in water column

Question 3

What happens when density of object does not equal that of water?

Answer 3

• it will rise or fall in water column

Question 4

What is positive buoyancy?

Answer 4

• density of object < density of water (floats)

Question 5

What is the specific gravity of positive buoyancy?

Answer 5

• <1

Question 6

What is negative buoyancy

Answer 6

• density of object > density of water (sinks)
