1)As there is frictional force,we can walk otherwise we would slip again and again and again.
2) We can turn a roadbend with maximum velocity as there is frictional force.
3)Frictional force neutralizes centripetal force in many case that is why a body remains in equilibrium.
4) A car can stop by applying brake is for frictional force.
5)we can rise a hill due to frictional force.
6)We can paint a wall for this reason.
