Air is a mixture of gases; oxygen, nitrogen, carbon dioxide and small amounts of various other gases. Air in motio can exert a force on an object. The study of air flow is aerodynamics. It studies how things fly through the air and how fluids or gases flow in a constrained area.
Air resistance is a contact force because you are in contact with the air in order to apply that force.
Air Pressure
The measure of the force due to air pressing on a surface is called the force.If you divide that by the area of the surface, then you have the pressure.
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
