Wings


Ever wondered why formula one cars have wings at the back? Yes, they are used as a stage for advertisements. Logically, it adds weight and it would not make sense to have it. However, there is a larger downward force with the wing at a 60 degree angle to the front. Going at speeds past 300km/h, the wind resistance is great, as it breezes past the car, it hits the wing and moves upward, pushing the car downwards, giving it an even larger aerodynamic force. We can thus see how Newton’s Third Law is actually in effect. The reason why the car is able to stay down to the ground is because there is an equal and opposite force acting downwards on the car when the air is brushed upwards.

Physics was actually able to make use of that to bring racing to a whole new level in the 1960s.
