Mechanical Energy :: essays research papers fc

Have you everwondered how a viridity aircraft lifts its tremendousweight off the ground, or what gives a runner the staying power to reach the finish line in a race? In orderto answer all these questions we must talk about(predicate)the variation of one sort of aptitude into some other. The jet aircraft gets its power from jetturbines. These compelling jet engines create ahigh-pressure stream of very impatient gases that pushthe aircraft forward as they leave the engine. Thisis an example of warming be trans influenceed intomovement. This is sometimes described asMechanical Energy. However, this transformationcould not take place without the terminate that theaircraft gets in spite of appearance its wings or fuselage. send away isconsidered a chemical energy. This diagram showshow the jet engine acts as energy to lift the aircraftoff the protrude of earth. Fuel house take the form ofgases, solids or liquids. When fuels combine withoxygen from the air, they release thei r storedenergy as heat. We disclose this process 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 weddedoff. Our bodies do not burst into flames but theperspiration on our strip down 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 sun 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 land or seas torise in temperature. The sun is very hot. Infact, the concern of the sun can reach temperatures of up to27 million degrees Fahrenheit. This is because ofanother kind of energy r eaction where newsubstances are continually macrocosm created as othersare being destroyed. This reaction is known to usas the Nuclear Reaction. Today we are trying toimitate this reaction in improving our energysupply. Scientists have calculated that the sun hasenough fuel to go on producing energy at itspresent rate for about five billion years. On earth
