does friction present during pure rolling??.....because as the bottom most point is in relatively at rest so we can say no friction....
but friction is generally required for the object to roll to give torque by which it has omega....
does the friction only acts initially?????and do it act throughout the whole motion....
SO...WHAT'S THE CONCEPT HERE....I'M QUITE CONFUSED....
help..if you know..
(no useless comments plzz)

Answer:
yes, friction present in during pure rolling:
as when we walk on the ground or on the earth floor then a force applied is a friction which pulls us forward and earth as a big source of mass is pull us forward and we are pulling the earth with less mass that's why the earth is able to to pull us with big mass and here are the friction works.
