Bernoulli's principle can be used to explain the lift force on an airplane wing. how must an airplane's wing be designed to ensure that bernoulli's principle is applicable? bernoulli's principle can be used to explain the lift force on an airplane wing. how must an airplane's wing be designed to ensure that bernoulli's principle is applicable? airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure. airplane wings must be designed to ensure that air molecules are deflected downward after hitting the wing. airplane wings must be designed to ensure that air molecules move more rapidly past the bottom surface of the wing, creating a region of higher pressure. airplane wings must be designed to ensure that air molecules are deflected upward after hitting the wing. airplane wings must be designed so that they are thick enough to ensure a significant pressure difference between the top and bottom surfaces of the wings.

Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure.

Explanation:

Swiss physicist Daniel Bernoulli proposed a principle for fluid flow, which can be stated as follows: "If the speed of a fluid particle increases as it flows along a current line, the fluid pressure must decrease and vice versa".

This knowledge allows us to understand why airplanes are able to fly. In the upper part of the wing the air velocity is higher (the particles travel a greater distance at the same time), therefore, the pressure on the upper surface is less than on the lower surface, which ends up creating a holding force from below to up.

With this principle, we can say that the wings of the airplane must be designed to ensure that air molecules move more quickly over the upper surface of the wing, creating a region of less pressure.

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.
