Mechanical Energy :: essays research papers fc

Have you everwondered how a sooty aircraft go ons its horrendousweight off the ground, or what gives a runner thestamina to stint the finish line in a race? In committo answer all these questions we must talk aboutthe transformation of maven sort of energy intoanother. The jet aircraft gets its power from jetturbines. These powerful jet engines create ahigh-pressure stream of very hot gases that fomentthe aircraft forward as they leave the engine. Thisis an example of heat being modify intomovement. This is sometimes described asMechanical Energy. However, this transformationcould not rejoinder place without the fuel that theaircraft gets within its wings or fuselage. Fuel isconsidered a chemical energy. This diagram showshow the jet engine acts as energy to lift the aircraftoff the surface of flat coat. Fuel can take the form ofgases, solids or liquids. When fuels combine withoxygen from the air, they release their investment trustdenergy as heat. We recognize this func tioning asburning. The individual relies on food for fuelwhich contains energy-giving substances that ourbodies can store until we need this energy to useour muscles. When we do use our muscles withinus, we may not always be sure that heat is givenoff. Our bodies do not burst into flames but theperspiration on our skin is a clue to what ishappening. The movement of the windsurfer has adifferent explanation. The windsurfer is propelledalong by a sail which collects mechanical energyfrom the winds that sweep along the water. Thisenergy has been produced by the sunniness whichwarms the earths surface and sets the air above inmotion. The suns heat comes to the earth as aform of radiant energy. When the heat reaches thesurface of the earth, it causes the domain of a function or seas torise in temperature. The sun is very hot. Infact, thecenter of the sun can reach temperatures of up to27 million degrees Fahrenheit. This is because ofanother diversity of energy reaction where newsubst ances are continually being created as othersare being destroyed. This reaction is known to usas the nuclear Reaction. Today we are trying toimitate this reaction in improve our energysupply. Scientists have calculated that the sun hasenough fuel to go on producing energy at itspresent rate for about tail fin billion years. On earth
