How are air resistance and friction similar?

Answer 1

Air resistence is actually a type of friction. We know that friction can be the force between to objects and air applies to this same notion. When an object travels at a high point in velocity it will feel air resistence. That's why you see space ships in space combusting into the earth's atmosphere because there is too much friction

Answer 2

SIMILAR: All friction involves two objects and the generation of heat. In this case the two objects are the surfaces of the plane facing forward (nose, leading edges of the wings and rudder, etc.) or the surfaces parallel to the direction of flight (wing surfaces, fuselage), and the air. As the plane moves through the air, the air (79% Nitrogen, 21% Oxygen) crashes into or around these surfaces and resists the movement of the plane (drag).

DISSIMILAR: Air is a fluid and obeys Newton's law of fluid motion. Hence, the atoms in the air closest to the wings and fuselage approach a relative velocity of zero, and the atoms farther and farther away from the wing have greater relative velocities. This shearing, essentially, of the layers of air is caused by friction. Since there is more friction closer to the wing and fuselage as the air is passing over, the air will move slower at that point. The air is more free-flowing further away from the plane and undergoes less friction at that point.
