can you imagine world without friction. why
Answers
Answer:
Without friction, I don't think the world would be anywhere nearlime what we know it to be now. So I will assume that friction disappears completely in an instant.
Forget about walking. You are able to walk only because of friction, which is the force which pushes you forward.
If friction were to disappear instantaneously, it would be bad luck for anyone in a moving vehicle - they would crash.
Since everything is perfectly smooth, many artificial structures like buildings will come crashing down.
You wont be able to hold anything in your hand. Thirsty? Want a glass of water? Sorry, you cant hold it.
Practically everything will change, and it will be chaos.

Nope, this kind of world is impossible.
Explanation:
A world without friction is impossible. Walking would be nonexistent, we would not be able to read (the book would slip from our hands, assuming the book somehow got printed), write(the pen wouldn't release ink and slides across the page), any and all lubricants would be useless( if there is no friction, why reduce friction?). Friction is the very base for human development. Without it, humans won't progress.
Oh, i forgot something. Humans wouldn't be able to live at all. The food would slip and fall from our hands before we put it in our mouths. :)
