Surface area, surface roughness, material composition are all factors.
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
the main causes of friction are molecular adhesion,surface roughness,and the plowing effect.
roughness of surface explain.... please..
weight ,roughness of the surface and applied force
the rougher the surface is, the more friction there will be
answer it yourself ;)

Surface temperature, Weight of the object, Roughness of surface and the object
Depend on what you need in surface roughness. Some process like fluid flow through pipe would minimized the surface roughness of the pipe to reduce the pressure drop while for floor surface coating require friction to prevent slip and so it determine whether the roughness would provide enough friction to prevent person walking to slip. Different roughness might need if compare between dry and wet floor.
weight ,roughness of the surface and applied force
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
The rougher then surface the greater the frictional force. When a surface is rough and you put friction to it, it creates sparks while smooth surfaces when friction is added causes a slight stactic shock.
1)increasing the roughness of the surface 2)increasing the mass of the object
