Friction of rough surfaces

Place two pieces of sandpaper together. Notice the friction that is formed when one is rubbed against the other. Now put some grease among the pieces of sandpaper. The friction is much decreased because the grease fills up the irregularities on the surface of the sandpaper. Applying grease to the moving parts of a machine acts in a same way
