displacement and buoyancy
buoyancy is the ability to float in a liquid such as water. archimedes’s experience with water displacement in the bath gave rise to archimedes’s principle, which states that the upward buoyant force, or push, exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces. in technical terms, buoyancy is the upward force exerted by a fluid on a body when the body is immersed in the fluid.
part a
making use of archimedes’s principle, displacements, and buoyancy, explain why some objects float on water, but others do not. use the diagram to you decide.
part b
the titanic is one of the most famous passenger ships in history. search the internet to determine how much the titanic weighed in metric tons.
part c
the hull of a ship should be the only portion of a ship that is below the water. therefore, at a minimum, how many tons of sea water should the hull of the titanic displace while it’s in water?
