Liquid and gases collectively called as a fluid.
Produces heat
Nature of the surfaces

When one surface slides or moves over another sliding or kinetic friction.
Kinetic friction
Sliding friction
When one surface rolls over another surface is known as rolling friction.
Independent of area of contact surfaces
Fluid friction
Wear and tear of machinery parts
Friction
