Sir why is the work done by friction equal to zero in case of pure rolling!

sir while calculating velocity friction is not considered but while calculating acceleration we have considered friction can you please explain this

Sir I had one doubt..... we are assuming that the friction on the bottom particle in the case of pure rolling is zero coz of the 0 relative motion due to which Vc and Rwc balance each other out. So how does pure rolling eventually come to an end in real life situations..... its not possible for pure rolling also to continue forever

sir in acceleration down the inclined plane of the body since point of contact should be at rest why is friction acting on it . please reply soon.

Ans 1 ->

It is a example of pure rollong so here only static friction is taken in consideration and because body is accelerating down the plane, friction is taken into consideration.

sir in pure rolling if point of contact is at rest how does motion takes place?why work done by friction in pure rolling is zero? please answer

Ans 1 ->

Firiction in an internal force thats why work done by it is zero
