An aircraft creates lift through a combination of various physical principles, including Bernoulli's principle, Newton's third law of motion, and the Coanda effect. We can look at each of these principles and understand how aircraft generates lift for flight.

Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. This principle is essential in understanding how the shape of an aircraft's wing, or airfoil, helps create lift. An airfoil is designed with a curved upper surface and a flatter lower surface. When air flows over the airfoil, it has to travel a longer distance over the curved upper surface than the flatter lower surface. This longer distance results in the air moving faster over the upper surface, which reduces its pressure. The difference in pressure between the upper and lower surfaces of the wing creates an upward force, which creates the lift we see in aircraft.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This principle is the basis for how an aircraft's engine propels it forward. The engine propels the aircraft forward, which then pushes the air over the wings to create the Bernoulli's principle to create the lift.

The Coanda effect is another important principle that contributes to the creation of lift. The Coanda effect describes the tendency of a fluid to follow a curved surface. This is why the design of the airfoil is so important. The air will flow over the wing while the lower flatter surface will simply let the air pass over it. Not following it in the same way as the upper surface.

In summary, the combination of Bernoulli's principle, Newton's third law of motion, and the Coanda effect all work together to create lift on an aircraft. The shape of the wing, combined with the forward motion of the aircraft, creates a flow of air over the wings. This flow of air results in a difference in pressure between the upper and lower surfaces of the wing, which creates an upward force – lift.
