The major cause of friction between metals appears to be the forces of attraction, known as adhesion, between the contact regions of the surfaces, which are always microscopically irregular. Friction arises from shearing these “welded” junctions and from the action of the irregularities of the harder surface plowing across the softer surface.

friction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion. About 20 percent of the engine power of automobiles is consumed in overcoming frictional forces in the moving parts.friction forcesfriction forces

Methods for Reduction friction:Make the surfaces little more smoother. ...Lubrication is another way to make a surface smoother. ...Make the object more streamlined. ...Reduce the Normal force acting between the surfaces in contact. ...Reduce the contact between the surfaces, so that less number of bonds will be formed.
