Thank you very much I got it but really what make me confused that I heard same story which happened to two of my doctors which that when they drove their cars suddnely they drove in black ice (Almost to be frictionless surface) their cars slid and they lost the control of their cars

That short while is more than enough to prove that:smile:

what I mean you can ignore the force of gravity and that device can helps you to do that:smile:

NASA has a device that works on making the force of gravity is equal to zero ,so we don't have force of gravity and we can make the room empty ( without air ) so we don't have air resistance for that we can get segma of force equal to zero:wink:

can we prove that in experiment?

so as I understood from you it will keep rolling forever? if that was your answer what do you say about the main thing in rotation which is the friction? if it keep rotating that means the friction is not Required for rotation motion ? so we can say that the ring (for example) can rotate or...

As I thought you have no answer for this problem

ammm there are two things I think about it the first one is the cylinder will rotate for a while then it will just slide but the problem here is the Newton first low said if there is no external force that means the object will stay as it is (if it roll it will keep rolling) but also we know...

hi everybody I have two questions releted to rolling motion and I want the answer for these questions if you can please the first problem: when a cylinder rolling in surface which has friction and suddenly the friction gone and the surface become frictionless. The question is will the cylinder...
