What is the weight of the object?
100
This will cause a vacuum on the top of a wing.
What is a higher velocity flow on the top of the wing from the bottom?

200
Why windows pop out of house when a tornado gets near it.
What is very fast swirling wind outside is much greater than the air moving in the house?
200

What is Pascal's?
300
How much force you have to place on a 1 m^2 area to create a lifting force of 1000 N on 200 m^2 that is connected by a tube of oil.
What is 5N?
300
