Have you ever wondered how airplanes are able to take off into the air and fly? Or why race cars have airfoils on their back sections? Both airplanes and race cars take advantage of Bernoulli's principle, also called the Bernoulli effect, to help control their movements. In the case of the airplane, it gets part of its lift from the Bernoulli effect. In the case of the race car, the Bernoulli effect helps to keep its wheels in contact with the racetrack at high speeds.
