Air Foil and Speed
If a jet in the air increases its speed, does the
downward force of air on the top of the wings increase or decrease? Does
the net lifting force of the air on the wings increase or decrease?
The downward force decreases, and the net lifting force increases.
Increase... if all else remains the same.
Reading more about Bernoulli's principle would help understand this.
I guess increasing the speed will lift the jet up.
My reasoning is that before the increase there is some uplift force that
balances the weight of the jet, keep it level. The uplift force is
directly related to velocity. If speed is increased, the uplift force is
