Polishing the surface or coating it with a lubricant is a way of reducing friction. To increase friction just hammer some ridges on the surface.

What happens to the magnitude of frictional force when two surfaces are pressed hard?
In my opinion , frictional force will increase
Does then frictional force depend on the type of surfaces in contact?
Yes. Different materials and different surface structures affect the frictional force.
What occurs when a force causes the speed of an object to decrease?
the frictional forces increase
Which frictional force is self adjusting force?
static frictional force
Is it possible for a frictional force to increase the mechanical energy of a system?
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.

Frictional force will increase with increase in?
Friction increases as a function of velocity.
Does then frictional force depend on the type of surfaces in contact?
Yes. Different materials and different surface structures affect the frictional force.
When do the frictional forces between two surfaces increase?
As they come into contact so tight friction would increase As roughness increases frictional force too increases.
Why machine parts oil occasionally?
to reduce the energy loss due to frictional force.
What occurs when a force causes the speed of an object to decrease?
the frictional forces increase
How does weight and surface area affect the frictional force?
As mass increases Surfaces area increase so the gravitational force increase so the friction increase...............
Does a frictional force between two objects increase with a force between them?
if you are talking about contact force, then you are correct. but if you are talking about some other external force,then the answer will be no. because frictional force only depends on the contact force between any two objects.
Which frictional force is self adjusting force?
static frictional force
Explain how frictional force is used to reduce the speed of a moving object?
Friction is a force that always acts in a direction opposite to that of motion. So the frictional force does negative work on the velocity of an object ( thus reducing the speed of an object).
Is writing on a paper a frictional force or muscular force?
i am sure that it is not frictional force.....
How do you decrease velocity of a moving car?
You increase the frictional force by applying the brakes.
