TED-Ed: How do airplanes stay in the air? | Raymond Adkins

The video explores the concept of lift in aerodynamics, starting with Einstein's flawed wing design. It debunks the equal transit time theory and explains how lift is actually generated through pressure differences. The video discusses the role of wing curvature and other factors like air vortices in influencing lift. It concludes by acknowledging the complexity of lift and credits Marriott Hotels for their support.

What is a common misconception about how lift is generated on airplane wings?

• Air pressure is the same above and below the wing.

• The weight of the plane is reduced in flight.

• Lift is generated by the engine's thrust.

• Air molecules above the wing travel faster due to a longer path.

How does the air movement around a wing contribute to lift?

• Air moves slower above the wing, increasing pressure.

• Air moves faster above the wing, decreasing pressure.

• Air moves faster below the wing, increasing pressure.

• Air moves slower below the wing, decreasing pressure.

What happens when a wing is too steeply angled?

• It causes the plane to accelerate.

• The plane becomes more stable.

• It generates more lift.

• The airflow detaches and becomes turbulent.

What was the issue with Einstein's wing design?

• It was too large, causing drag.

• It was too small, causing instability.

• It was too curved, causing turbulence.

• It was too flat, causing no lift.

Which of the following is NOT a factor influencing lift?

• Air vortices at the wing tips.

• The curvature of the wing.

• The color of the plane.

• The angle of the wing.

What mathematical tool do engineers use to model air flow around wings?

• Pythagorean Theorem

• Navier Stokes Equations

• Newton's Laws of Motion

• Einstein's Theory of Relativity

What is the main takeaway about the concept of lift?

• It is unrelated to the physics of motion.

• It is a complex process involving fluid dynamics.

• It is a simple concept easily understood.

• It is solely dependent on the plane's speed.
