mechanical energy

A detailed Summary of mechanical energy


MECHANICAL ENERGY Have you ever wondered how a jet aircraft lifts its tremendous weight off the ground, or what gives a runner the stamina to reach the finish line in a race? In order to answer all these questions we must talk about the transformation of one sort of energy into another. The jet aircraft gets its power from jet turbines. These powerful jet engines create a high-pressure stream of very hot gases that push the aircraft forward as they leave the engine. This is an example of heat being transformed into movement. This is sometimes described as Mechanical Energy. However, this transformation could not take place without the fuel that the aircraft gets within its wings or fuselage. Fuel is considered a chemical energy. This diagram shows how the jet engine acts as energy to lift the aircraft off the surface

of earth. Fuel can take the form of gases, solids or liquids. When fuels combine with oxygen from the air, they release their stored energy as heat. We recognize this process as burning. The individual relies on food for fuel which contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects mechanical energy from t
