three types of friction exist they are static friction a cycle model and its that it is because of static force between the road and types sliding friction in order to make the Duster on the blackboard the teacher apply supports the friction between the duster and the board is known as sliding force rolling force when a spherical ball 100 Floor it will stop after travelling some distance this is due to rolling friction between the floor and the spherical body

Answer:
Methods for Reducing Friction
☆ Moving parts of machines are covered with oil or grease, which make the effect of friction less.
☆ The surfaces are highly polished, to eliminate the irregularities thus making the surface smooth and reducing friction to a great extent.
☆ Fluid friction is reduced by using streamlined shapes in airplanes or ships.
☆ Use of wheels between surfaces moving over each other reduces friction as rolling friction is less than the sliding friction.
☆ Ball bearings are used in machines to reduce friction. These are tiny steel balls often placed between moving parts of machines which reduces friction and saves a lot of enery.
