The surface that has the lowest friction is a wet surface, or a surface that has been oiled with light oil, or the air cushion underneath a hovercraft. Then there is the train that runs on magnetic rails, hovering above the rails without physically touching.
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
more rough surface more friction object have
Plane surface with negligible friction.
Rough surface provides lot of friction.

Surface friction ALWAYS point parallel to the surface and opposite motion. There must be a normal force for there to be friction

friction
the rougher the surface is, the more friction there will be
the smoother a surface is, the less friction it produces.
Rough surface provides lot of friction.
if the mass is more than the friction is high. and if the surface is rough then also the friction is more. thus we can say that both mass and surface type affects friction.
A force that resists motion of one surface across another surface is called FRICTION(or FRICTIONAL FORCE)
Depending on the roughness or smoothness of the surface, it will increase friction if it is rough,(which has more microscopic hills and valleys). If the surface is made of a smooth material, it will decrease friction
