Write your opinion in minimum 50 words]]> 2017-11-07 16:14:47 UTC https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/204430941 Friction is a necessary evil https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/204748735 2017-11-08 11:17:21 UTC https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/204748735 Friction is a necessary evil. https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/204753203 Friction is necessary:
If there is anything which moves forward with respect to something else while in contact with it without any external force acting it's because of god damn friction. Example, walking human, rolling tires.









Friction is evil:
If there is external force available then the same friction slows it down. Example, reciprocating piston in cylinder.

ADVANTAGE-
It  helps us to  walk, write , playetc.

DISADVANTAGE
Due to it  various energies are wasted like  heat energy.
It opposses the motion.  

Thats why FRICTION IS A NECESSARY EVIL]]> 2017-11-13 11:48:21 UTC https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/206179595 FRICTION A NECESSARY EVIL https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/206217776 Friction is a necessary evil. Without friction we are handicapped.We need friction between the shoe and the ground to walk . It is this friction which allows us to walk.The same way it helps us to write, drive a car and fixing the nail.Not only this, it produces heat in parts of machines. We have to exert more power in machines. So it has its advantages and disadvantages]]> 2017-11-13 13:43:00 UTC https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/206217776 friction is an necessary evil https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/206220747 There are many forces one of them is friction. it is also very important but it is a negative force .without friction we would slip and not able to do work.But because of friction the machines produces more heat and noise. ]]> 2017-11-13 13:48:36 UTC https://padlet.com/darshanasinha36/bppoqfw6evbp/wish/206220747
