What is difference in ball rolling and ball slipping what are the forces in each case and how they move if ball is rolling as well as slipping

Question

Rolling and slipping

Answer 1

There is less frictional forces acting on a ball rolling than a ball slipping .  This is because in rolling, there are many points of contact with the surface, whereas in slipping, there is only one point of contact.  It is easier to roll a ball on a surface of contact than to slide it.

 

If you were to roll yourself across the floor, almost every part of your body will touch the floor.  If you slide yourself across the floor, then only one part of the body will be in contact with the floor.
