Millions of dollars of research and experimentation have been invested in car designs to minimize the adverse effects of air resistance. And here is the American household negating all efforts to maximize gas mileage with outdoor gear strapped to the roof. Most of the fuel cars consume is to counteract the air resistance. If there were no air resistance, the only force slowing the car would be the friction between the tires and the road. This small force would hardly retard the motion with little need for additional fuel. The example presented in this chapter is that of a stone falling with no air resistance to the more realistic situation where air resistance retards its motion.
