Hello
well i have a very basic doubt
well when we have a rolling motion
and surface is rough
then what i used to do was write linear and translation equation and find f (Frictional force)
Now is this frictional force same as static friction and can we write is as kmg where k is coeffecient of static friction assuming since point of contact is at rest so static friction acts.
Please help
further if friction acts during rolling motion we know energy remains conserved and no dissipation takes place but does that mean frictional force does no work
thanx
