How air friction affects motion of objects like cars and bicycles explain how air friction is reduced in each case?

Answer:
Air resists the motion of an object , the faster it is the more fricition there is . Aerodynamics is an independent part of science where people study the effect of air on objects in motion , thus the creation of more inclined surfaces and several geomatric shapes to reduce airi resistance.
