Question

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?????bcz how could it act if the point of contact is relatively at rest....????
SO...WHAT'S THE CONCEPT HERE....I'M QUITE CONFUSED....
help..if you know..
(no useless comments plzz)

Answer 1

Answer:

In pure rolling motion, friction causes the wheel to catch and stops the sliding and slipping motion; for example when a car spins its tires, slipping is taking place, thus the frictional force works to stop the spinning out and causes the tires to catch and begin pure rolling motion

Explanation:

Hey buddy the main concept is that there is friction in pure rolling too becuz the surface always have some irregularities
