Car body??

Question

How does a formula 1 car's front spoiler create downforce? Does it use newtons third law or the bernoulli principle? plz explain how it creates downforce. How does a car body create downforce? Does it use newtons third law or the bernoulli principle? Plz explain how it creates downforce. How does a rear spoiler create downforce? Does it use newtons third law or the bernoulli principle? Plz explain how it creates downforce.

No a front wing and a rear wing not a spoiler. Change the the spoiler to wing

Answer 1

The creation of down force whether on the front spoiler(or wing) or rear spoiler(or wing) on a car is achieved through the air flow around the spoilers which is shaped like an inverted wing of an aircraft. That is to say that the down force attained on the car through the spoilers which are shaped like an inverted airfoil and the force is created using the principal of Bernoulli, which states: P + 1/2 (Rho)V^2+rho*g*z =constant.
Where P = pressure, Rho is the density of air, V is the velocity of air, g is the acceleration and z is the height above ground.

The differential pressure acting on the inverted wings creates downward force which pushes the wing (Spoilers) in a direction towards the ground. For the front spoilers (wing), the force is downwards against the front wheel. For the rear spoilers (wing), the force is downwards against the back wheel. These forces can create moment around the center of gravity of the car.

Answer 2

The Bernoulli Principle.

Basically an airplane wing mounted upside down so it generates downforce instead of lift.

Answer 3

Simply put;
The downward force is created by deflecting air upward. Action & reaction.
