Methods used for Reducing Friction

Answer: Make the surfaces a little shinier. Friction is increased by rough surfaces, while friction is reduced by smooth surfaces. Making a surface extremely smooth will increase friction by forming a large number of bonds.

Another way to make a surface smoother is to lubricate it. A lubricant is a slick substance that is used to reduce friction between two surfaces.

Improve the object’s streamlined appearance. A streamlined shape allows air or water to flow freely around it with the least amount of resistance.

Reduce the normal force acting on the in-contact surfaces. The higher the friction, the stronger the normal force acting on the surfaces.

Reduce the amount of contact between the surfaces so that fewer bonds are formed. The best shape for reducing friction is a sphere.
