    First of all, it is friction force, not fictious force.

    Friction force is a force that sort of blocks objects from moving due to brushing to other objects, gases, liquids. However, it cannot actually move something, only restrict a movement, so it's work will aways be negative or zero.

    Some materials have interesting properties. For example Helium (the isotope with 4 protons) when cooled to ultra-low temperatures (4 kelvins) becomes 'supraviscose'. It can flow frictionlessly.

    A fictitious force is a force that is experienced within an accelerating reference frame. This "reference frame" could be a moving car for instance. If you suddenly apply the brakes, you will feel as though you're being pushed forward. In reality you're not being pushed: the car is being pushed backwards by the force applied by the breaks and your body just moves forward the way it did before you used the breaks. This is why you should wear seatbelts🙂

    See also wikipedia, I think the examples illustrate the concept best.
