• Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
• Lubrication is another way to make a surface smoother.
• Make the object more streamlined.
• Reduce the forces acting on the surfaces.
• Reduce the contact between the surfaces.

Answer 2

Answer:

hope it will help u..

Explanation:

By using lubricants: These are applied to surfaces to reduce the friction between the surfaces. Example Oil, wax, grease and castor oil. 2. With the help of polishing the surface: We sprinkle fine powder on the carrom board and then we polish its surface to make smooth so that the striker slides easily on the surface. 3. By using ball bearing: We use leadshots in bearing of a cycle hub because rolling friction is smaller than sliding.
