SCIENCE AND IMAGINATION HAVE NO BOUNDARIES

An incident that happened in a boring engineering mechanics class in my last semester, shown me that science and imaginations have no boundaries....

Professor in that class was dealing with a chapter called friction.He was a bit addictive to usage of  Figurative English.He said" you cant imagine the existence of world without friction". 

This openly challenged my ,then , sleepy mind,asking me "why cant i???"

Then it slid into imaginations,... assuming there was no friction , i could see a girls' face fall down on the desk which was resting on her hand, sir suddenly falling with his back on ground(wow).. all these because --" NO FRICTION"

After classes were over i got into the college bus to return to home, my mind still was in the same imaginative arena.

Without friction the Wheels were running i mean rotating but the bus was not able to move a inch.

i saw a motor cycle moving, and huh this motor cycle could not stop as there was no friction ,as it cannot apply any force to stop on the area of contact....

after several flashes like these , i came out with a interesting relation between inertia and friction...!!!!

According to Newtons inertia law(1 st law) "Any body in rest or motion will continue in that state till encountered by an --external force--"

The --external force-- in our day to day life is friction,

Friction is applied by the objects due to nature of surfaces under relative motion, this application is so common that we even don't feel friction exists!!!

Consider that there is a switch for ON-OFF of existence of friction on earth...

Imagine buses moving,people walking,sitting etc ,some preparing to start a walk.....

Now i fly all the way to the switch . i put it off!!

Now even the bus i mentioned earlier , wants to stop ,it simply CANT...

...the person who was walking before switching off friction cant  stop!!

The man willing to walk ,cant start moving.(reader should posses a bit of imagination !!).. all these because there is no opposing force ie without friction no body can change its state ...

Which is directly related to newtons 1st law... ie inertia

This is how a simple or silly imagination led to a simple but yet interesting and commonly unexplored relations between two different entities ....

So always try to do what mind says .. it will always lead to interesting relations .. known or unknown... 

so let your mind free.. let it fly
