Why we can stretch a Rubber ball but not a Stone?

-
Interesting questions. I asked this kind of curious questions in my childhood; that was a great experience. Okay now let we see what will be the answer of this question according to Science.


Well, there is a term in physics called elasticity.  It is defined as, "the property of a body by virtue of which it tends to regain its original size and shape when an applied force is removed".

This definition tells us, when we applied a force on a object then their will be some changes in it's original size and shape; but if it regain previous size and shape then that kind objects are called elastic in nature. And this nature of an object decide that how much it will regain previous size and shape. 

On the other side, if you are applying a force on object; and it have no gross tendency to regain their previous shape and get permanently deformed. Such matters are called Plastic and this property is called plasticity.

Now I hope my readers are aware of two physical properties and these two properties are the answers of this question. 


In our question we have two objects one is rubber ball and other is a stone. Suppose we hit these two objects with a hammer 🔨. Then we will see that, rubber ball regain its shape and size while stone is broken into many peices. So, rubber have an elastic property while stone have a plastic property. 


Due to this, rubber ball can stretch and regain its shape while stone cannot stretch and broken down into many small peices. 

This experiment is very simple, you can also do this and check. Kindly note that children will do this under guidance of parents as hammer can harm you.

I hope you get a clear answer. Write about today's article and share it.

10 Minutes Focus Theory for Controlling Mind

Hello everyone, most of us specially students are complaining about the lack of concentration, specially about their inability to complete scheduled study time table. There are many reasons for this phenomenon in general, if we will going to discuss those; but here we are trying to provide a solution with taking minimum time of yours. So, let's directly focused on method and solution. This method is call , 10 Minutes Focus Theory for Controlling Mind , basically I started this method on myself some time back and I found good results from this. That's why I am sharing this with all of you on my blog.  In this method, when you are bored or lost interest from work or study, you should have to take extra 10 minute time for ending work,  reading or studying or something else. You have to say to yourself that,  ' I am taking these LAST 10 Minutes and after that I stop doing this work, but in these 10 minutes, I must give my 101%; so, I have to forget whole World for ONLY these 1

How does a Compass work?

-

A magnet will always point North-South direction, because it is attracted by the north and south magnetic poles of the planet Earth. This property is used in a compass. A small needle-like magnet with its north and south poles marked is balanced on a pivot. The pivot is placed in the centre of a card with all the directions (or points of the compass) marked on it. If a traveller or person positions the compass so that the needle lies along the north-south line on the card, he can read off the direction in which he is going. Compass is very useful. For example, long ago in past, sailors of all around the World were navigate by using the Sun’s position in Daytime and Star’s position in Night time. But, sometimes, it was too cloudy for them to see the Sun or the Stars and so they did not know which way they have to go. The compass revolutionized sea travel because the sailors could find their way whatever the weather is. A compass needle points to the Earth`s magnetic poles. The navigator

What is electromagnet and its use?

Most of us noticsed that, a compass needle will only point North –South, if there are no other magnets near it. But, if there are magnets near compass, the needle will be attracted towards them and will point in a different direction or be deflected. And it was discovered that if a compass was held near a wire carrying an electric current, the needle was deflected. But if the current was switched off the needle swung back and pointed North-South again. This meant that the current was acting like a magnet. If some wire is wrapped around a magnet and a current passes through the wire, the magnet will become much stronger. This is known as an electromagnet. Use 1 . Used in Computer Hardware and Memory Storage Devices. In these devices, data are stored in electromagnetic format in bits and bytes form. Even the computer hard ware is having a magnetic tape which works on the electromagnetic principle. Not limiting to this, the olden day VCR’s are having huge rolls of magnetic tapes, which ha
