thanks all of you for the quick reply.
what i understand from this discussion that there will be a friction force beteen the object and its axis, which in turn at some point in time will stop that object rotation.
please correct me if i am wrong.
Now, Can we relate vacuum with the zero...
Any object rotating on the axis does stop because of some kind of friction force.
What happens if the same object rotates in the vacuum ?
does the friction force applies to it ?
or does it stop at any point in time ?
or does it continue to rotate forever ?
Thanks & Regards,
