Ok so my science class is doing this project where we have to find the physical science of things. Like for example what's physical of an electric toothbrush or like the physics of how a scyscraper is built. What im having trouble finding is the physics of an owl flying. Like what's physical about that? The way it flaps it's wings? Please help i need this.

andandand also the physics of a digital camera and a ship too!

Flight is based on Bernoulli's Principle. This principle states: As the velocity of a gas increases, its pressure decreases; and when the velocity decreases, its pressure increases".
Wings (of birds and airplanes) are curved - flat on the bottom of the wing and curved on the top surface of the wing. As a result of this curvature, the air traveling over the top of the wing has to travel a greater distance than the air going under the wing.
The air going over both surfaces reaches the back of the wing at the same time. Therefore, the air going 'the long way' (over the top of the wing), must be traveling FASTER than the air going under the wing.
From Bernoulli's principle we can see that the faster moving air going over the top of the wing will put LESS of a force on the wing than the slower moving air going under the wing. The net result is lift!
Hope you find this helpful. Best wishes and good luck.
