Question

help me... please explain the "measuring the buoyancy as a function of the immersed depth"

Answer 1

ok so first, Archimedes' principle is a good place to start. It simply states stuff immersed in water (or any fluid) will have a buoyancy force acting on it. This force pushes it up if the stuff is in is less dense then water (or whatever liquid its in) and pushes it down (the opposite of up) if it is more (the opposite of less) dense then the liquid it is in. Duh...?

Thats not all...Archimedes' principle also tells us the magnitude of this force nears earths surface, (how strong it is exactly) is equal to: Force = (mass of stuff)*(gravity constant 'g'). (direction or sign of this equation depends on if you're stuff is more dense or less dense then whatever liquid its submerged in)

So back to "measuring the buoyancy as a function of the immersed depth"
A function of something means how it behaves or changes with respect or regard to some quantity. In this case, the quanity is implied within the sentence, and it is immersed depth. So another way to view "measuring the buoyancy as a function of the immersed depth" is as "how does the force described in Archimedes' principle change over time with respect to immersed depth, or how deep it goes under the water" The answer is, from the second part of Archimedes' principle,Force = (mass of stuff)*(gravity constant 'g'). note that another way to write mass of stuff is 'volumn of mass in question * density of mass in question' as it often is in textbooks. Also note that this is a linear force, not exponential so it is very like Hooks law and springs if you understand those concepts well then dry to draw analogies.
