Gravity vs Gravitational force

   Okay. a lot of people mess this up. Gravitational force may be present between any two bodies having some mass whereas Gravity is the force between a body and the Earth.
   When you talk about your weight, you are actually talking about your mass. Suppose if you say your weight is 50 kg, you will be wrong. Your mass is 50 kg. Your weight is actually 490 Newton (appr). Your weight even varies from place to place, even on the Earth.
   Actually, its not only the Earth that exerts force on you.Even you exert force on the Earth, which is in fact equal and opposite to the force it exerts on you (your weight that is). You dont notice it though. Its because it requires more force to displace the Earth than it does to displace you.
  Moral of the story is, no matter what people say, even you are attractive, literally.

Tough as Steel? Think Again

You think steel is strong huh? Well it is, until it meets it match that is.
You hang a steel wire by the roof and hang a load on it. When I say load I mean LOAD. It will stretch for sure. You will notice that as you keep increasing the load, there will come a time when it won't resist stretching and start flowing - almost literally. Eventually it will reach the breaking point.
 Well let's have a show of hands. Who thinks they are tough as steel now, huh?

Bouyant Force

The magic is here isn't it?
Buoyancy is one of the most fascinating forces I have studied. As Mr. Archimedes stated
                   " Any object when fully or partially immersed in a fluid experiences a force which is equal to the weight of the fluid displaced."
                  It simply means that if you dip anything in a liquid, it will feel lighter. How light, it depends on how dense the fluid is and how much space the object in question is occupying.

Physics - We love it

Don't we all just love Physics!
I remember when I five, I was fascinated by mirrors. I used to stare at them all tthe time, wondering if they were a portal to a different world.
I analysed them further and co-related all my observations. I even independantly derived the laws of reflection(I am neither bragging nor claiming any credit). Such was my fascination towards the subject. That is to say - that I was in love with Physics even before I knew what the word meant.
When I went to High school I discovered that it was indeed a subject of study - and the bond grew stronger.
Till this day, my fascination hasn't decreased a bit. I still keep staring at stuff and keep trying to think what it means.
So this blog is an initiative to bring together all the people who share the fascination and indulge in the pleasures of Physics.
