Jan 29, 2025 · Here is the part of the textbook that led to confusion: Question: Why do we not regard the weight of the cylinder when calculating the buoyant force? As I learned previously, …

Mar 29, 2020 · Viewed mathematically, buoyancy is then just an application of the Gauss theorem of vector calculus, whereby a surface integral (force on a surface due to fluid pressure) is …

Wikipedia also suggests buoyancy is due to the pressure differential of the supporting fluid, unless I misunderstand. This just doesn't make sense, because the upwards force is proportional to …

The answer hinges on Archimedes' principle wiki. If the object is denser than water it is more massive than the water that it displaces. This means that the object experiences greater …

Apr 16, 2017 · Why does an object sink when filled with water, even if the same object would float without water inside? For example, put an empty glass cup into water, and it floats. But if you …

Jan 10, 2021 · Why isn't buoyancy affected by the object immersed in water? I know that more depth means more pressure means more buoyancy. But based on Newton 3rd law, the water …

Sep 22, 2022 · 1 Buoyancy Let's write the resultant force due to pressure acting of the surface of the body. For a body of general shape, we would integrate the elementary action on the …

Apr 27, 2011 · Given I have two identical balloons on earth, how will the buoyancy compare between the one filled with helium and another filled with hydrogen? How can I calculate the …

May 1, 2014 · Edit: For completion, since it is raised as a question in the comments Melting icebergs boost sea level rise, because the water they contain is not salty. Although most of the …

I was watching a special on divers who dove down hundreds of feet without tanks or gear. The show referred to a depth at which the diver was no longer buoyant and would actually sink, …
