The physics behind F1 cars are like that of aircraft wings he studies, except in F1 cars, downforce is the objective rather than lift off, i.e. for aircraft wings, the aim is to make the air above go faster to provide a net upward lift. In the case of F1 cars, they need to be as fast as possible, but also safe. Therefore, it is important to have enough downforce to prevent the car from "flying off" and provide more grip. Explain in terms of fluid mechanics how the front wing of an F1 car provides majority of this downforce, what would be the effects of a damaged front wing, and why in most cases a pit stop will be necessary to change it
