The lift generated by an airplane wing is primarily explained by Bernoulli's Principle. This principle states that as the speed of a fluid increases, its pressure decreases. When an airplane wing moves through the air, the shape of the wing forces the air above it to travel faster than the air below it. According to Bernoulli's Principle, this increase in airspeed over the wing results in a decrease in pressure above the wing compared to the pressure below it. This difference in pressure creates an upward force, known as lift, which enables the airplane to rise off the ground.

In contrast, Archimedes' Principle pertains to buoyancy in fluids and does not specifically explain lift in the context of flying. Newton's Law, while relevant in terms of action and reaction forces, does not directly address how wings generate lift through fluid dynamics. Pascal's Principle, which involves the transmission of pressure in confined fluids, is also not primarily responsible for lift generation in an airplane wing. Thus, Bernoulli's Principle is the most suitable explanation for the lift created by the shape and speed of air over an airplane wing.
