Question

how does flying defy the laws of physics?
i know it seems really random and easy but i really need some help

Answer 1

It doesn't so much defy it as the principles behind aren't understood.

Check the Straight Dope, or do a Google search.

Answer 2

For the first note, and this is to the other answerers: FLYING DOES NOT INVOLVE BOURNELLI'S PRINCIPLE, NOR DOES IT INVOLVE CREATION OF DIFFERENTIAL PRESSURES ABOVE OR BELOW THE WING.

Secondly, nothing can defy a true law of physics. At best, the law is innacurate and needs to be changed. In flight, the air strikes the angled bottom of the wing and bounces off in a downward direction. By Newton's laws of motion, for every action there is an equal and opposite reaction... this pushes the wing up. If you've ever stuck your hand out of a car's window on the freeway, you're well aware of how a wing works (without bournelli's principle, i might add). Thus, Newton's laws explain why flight not only fits with the laws of physics, but also makes perfect sense considering the construction and manipulation of aircraft.

Answer 3

Flying does not defy the laws of physics. It's simply manipulation of air pressure above and below the wings generally speaking. Take birds from example:

Answer 4

Flying doesn't defy physics, it proves them. Bernoulli's law states that a fluid (air) moving past a point reduces pressure on either side of that point. Because the shape of an airplane wing or bird's wing is cantilevered, the air has a longer path over the top of the wing than it does over the bottom. This results in reduced pressure above the wing's surface, enabling flight.

Pitchers throw curve balls using the same principles.

Answer 5

Flying does not defy laws of physics,instead there is much of physics involved in flying,example bernoulis etc.

So you must be very confused at the whole dynamics of flight do some search on the web and you will come to know.

Answer 6

flying does not violate physics.
When air passes over a wing, it creates less pressure above the wing than below the wing. The pressure below the wing is stronger than the pressure above the wing, so the wing lifts up, and takes the rest of the plane along with it.
The air is doing most of the work. The engine just pushes the plane forward to generate enough velocity to make the airfoil work.

Answer 7

nothing that we observe can defy the laws of physics, if it happens then it changes the laws.
