Energy and its sources



Energy is a thing ,or say, a quantity which is present all around us. Energy is the quantity of work. This is what we learn in our physics book. There are many types of energy. Mechanical energy, Electric energy, Wind energy etc. These are something which we see constantly in our daily lives. Energy is the capacity of doing work. For a man, typing something in the computer needs energy, as I am doing. Everything which moves possess energy. A moving body does work against many things, such as friction, etc. and releases energy at the same time. Therefore we can say, for doing a work we must have some energy inside us which must be released to do that particular work.



For acquiring energy we must eat food and drink much water (for humans). It is said that if we don't drink water for a day or two then you can die, this was said to me when I was a small kid. So I suggest you drink water and eat food and complete your diet and the proper time.

Sources of energy would mean that from where we can get energy. For human beings. energy can be procured by eating food. But there are many other energy which are important for the proper functioning of humans in this modern world. We need electric energy which we get from nuclear reactors and many other sources. Humans are the most developed species in this nature and they have found the way to procure energy from the wonders of nature. So, we can say that the different sources of energy, such as, nuclear reactors wind mills etc, are of the greatest inventions in this beautiful world. and we all must know its value.




Also remember ..... Energy can neither be created nor destroyed (Law of conservation of energy, read in my science book).

"Energy is something which we get to use and also we have to return that energy by doing any work."

Thank you. This was Arun Kumar blogging for you.
