Question

The downward force produced when air flows over the winglike spoiler on a race car is an example of ___ principle

Answer 1

Bernoulli's Principle

Answer 2

As per bernoulli's principle

`P_1 + (1)/(2)\rho v_1^2 = P_2 + (1)/(2)\rho v_2^2`

here

`P_1` = pressure upwards

`P_2` = pressure downwards

`v_1` = velocity of air upwards

`v_2` = velocity of air downwards

now from this equation we can say that the pressure difference will be

`P_1 - P_2 = (1)/(2)\rho v_2^2 - (1)/(2)\rho v_1^2`

now the force due to this pressure difference will be

`F = (P_1 - P_2)A`

so this is the above force which is given above
