Question

question 2 of 10 as air molecules move over and under the wings of an airplane, the pressure increases below the wings to create which of the following? a. lift b. weight c. gravity d. thrust

Explanation:

When air molecules move over and under the wings of an airplane, Bernoulli's principle is at play. The shape of the wing (airfoil) causes air to move faster over the top and slower below. According to Bernoulli's principle, faster - moving air has lower pressure and slower - moving air has higher pressure. The increased pressure below the wings creates an upward force known as lift. Weight is the force due to gravity acting on the mass of the airplane, gravity is the general force of attraction between masses, and thrust is the forward - moving force provided by the engines.

Answer:

A. Lift
