How do airplanes actually fly? - Raymond Adkins

Guided Notes
Key concepts students will learn:
- •
An airplane wing generates lift because the air traveling above the wing moves faster than the air traveling below, creating an area of lower pressure.
- •
A common, but incorrect, explanation of lift says that air molecules above and below the wing must meet at the same time, but in reality, the air above reaches the wing's trailing edge much faster.
- •
If a wing is too curved or steeply angled, the airflow above may detach and become turbulent, which can reduce lift.

“Explain how the speed of air moving around a wing affects the pressure, and how this pressure difference creates lift.”
