Summary on Work, Energy and Power

Summary on Work, Energy and Power -
Hear is an important topic i have to share and debate with you all. Summary on Work, Energy and Power is an important think in our day today life. In physics, however, the word ‘Work’ covers a definite and precise meaning. Somebody who has the capacity to work for 14-16 hours a day is said to have a large stamina or energy. We admire a long distance runner for her stamina or energy. Energy is thus our capacity to do work. In Physics too, the term ‘energy’ is related to work in this sense, but as said above the term ‘work’ itself is defined much more precisely. The word ‘power’ is used in everyday life with different shades of meaning. In karate or boxing we talk of ‘powerful’ punches.

Law of conservation energy is also an important think to debate on. Let us see what is actually taking place in the following examples

• Steam engine- Here the coal burns and the heat due to the combustion of coal converts water into steam and the expansive force exerted by the steam on the piston of the engine moves the locomotive
• Hydroelectric power plant- Here water stored in a reservoir is made to fall on turbines which are kept at a lower level and which in turn are connected to coils of an a.c. generator

Law of conservation of energy states that the energy can neither be created nor destroyed but can be transformed from one form to another.

I hope this was more interesting and meaningful to you all. I am very sure that i have enlightened your mind to learn more on Physics. No problem i will help in all the topics on Physics Help. Keep reading and leave your comments .........
