Essay on physics of submarines - most people have some sort of familiarity with submarine crafts most of which are most likely related to the navy this is a very accurate depiction of submarines, as they are primarily used for this, however, they are used in areas of scientific research as well the purpose of this web page. The objective of passive acoustics is to detect the sounds produced by a submarine, such as propeller, engine, and pump noise these sounds can be identified by experienced sonar operators each type of submarine has a unique sound profile that makes up the acoustic “signature” of the vessel. Look at the essay 'advanced physics essay, the laser' for high school and college students unit – iv advanced physics syllabus:lasers- spontaneous emission, stimulated emission, population it is used in cable television, space vehicles, ships & submarine cable 8 it has wide applications in.
Like other ships, a submarine can float because the weight of the water that it displaces is equal to the weight of the ship this means the pressure of the submarine pressing down on the water is the same as the pressure of the water pushing up on the ship this phenomenon is called buoyant force buoyant force works the. We will also look at how a submarine works, from a physics standpoint the history of submarines 332 bc aristotle described a type of submersible chamber used by the sailors of alexander the great during the blockade of tiros [tags: physics sea ocean submarines], 2080 words (59 pages), powerful essays, [ preview. Comhow does a a submarine has discuss your physics questions online at www physics4spmcom36 understanding bernoulli's pressure of the moving airthe higher atmospheric pressure decreases as the speed of the airwhich acts at the bottom of the increasespaper pushes up the paper.
Submarine a)freezing point must be low=because the temperature is low b) material must be be strong=to withstand pressure c)corrosion rate must be low= as sea water is a good corrosive agent d)size of the ballast tank must be large=to enable the submarine to submerge deeper into sea e)use thick wall=because water. See the paper by edmunds and mccafferty (1988) for more details on this interesting transition on the below that depth humans need to be encased in structures (submarines, hard diving suits) that bear the pressure of the water, leaving the human at normal pressure further reading - physics. Welcome to my web page on submarines i hope to explain to you a little bit about the way submarines work they are very complicated machines, and to try and cover every aspect in detail would be pretty overwhelming so i am going to touch on a few of the concepts about submarines that i find the most interesting:.
Most people have some sort of familiarity with submarine crafts most of which are most likely related to the navy this is a very accurate depiction of submarines, as they are primarily used for this, however, they are used in areas of scientific research as well the purpose of this web page is to go into the history of the. A periscope is an instrument people use to look at things from a hidden position the device has a long tube with parallel mirrors situated at both ends at a 45- degree angle however, some periscopes opt for prisms rather than mirrors, such as those in submarines the military typically uses periscopes in.
A submarine (or simply sub) is a watercraft capable of independent operation underwater it differs from a submersible, which has more limited underwater capability the term most commonly refers to a large, crewed vessel it is also sometimes used historically or colloquially to refer to remotely operated vehicles and. Facts about submarines you may have seen a submarine on television or in the movies this large, powerful underwater vessel is a cool way to explore below the sea we also depend on them for many things read on to discover all about the submarine we will be exploring the history of the sub, what it is used for and. Although it was a complete military disaster, british submarines were not a complete disaster the ultimate impact of british submarines in the dardanelles was not great in the sense that they did not change the course of the campaign however, they had proved that they were a valuable weapon when used properly.
In this science fair project, investigate how submarines use propellers and stabilizing fins to move forward. After decades as laboratory curiosities, some of quantum physics' oddest effects are beginning to be put to use, says jason palmer improved gravity sensors would be able to spot moving masses under water, such as submarines or torpedoes, which could wipe out the deterrent effect of french and british nuclear.
