Questions and Answers

Why is the upper surface of an airplane wing curved more than the lower surface?

To decrease weight
To increase lift (correct)
To reduce drag
To improve stability

What is the name of the principle mentioned by Chris that explains how airplane wings generate lift?

Einstein's Theory of Relativity
Newton's Law
Bernoulli's Principle (correct)
Archimedes' Principle

Why does the air going over the top of the wing have to move faster than the air below?

To maintain stability
To meet the air on the other side (correct)
To increase drag
To decrease lift

Match the following statements with the correct terms:

Airplane wing's upper surface is curved more = Intentional design Air going over the wing's top moves faster = Bernoulli's Principle Air moving faster has lower pressure = Bernoulli's Principle Lower pressure sucks the plane up = Airplane lift Signup and view all the answers

Match the following terms with their definitions:

Bernoulli's Principle = The principle that states faster moving air has lower pressure Airplane lift = The force that pulls the airplane up due to lower pressure Intentional design = The design of airplane wing's upper surface being more curved Air elasticity = The property of air that allows it to meet on the other side of the wing Signup and view all the answers

Match the following phenomena with their causes:

Airplane lift = Bernoulli's Principle Faster moving air over the wing = Curvature of airplane wing Lower pressure = Faster moving air Air meeting on the other side = Elasticity of air Signup and view all the answers

Match the following terms with their effects:

Bernoulli's Principle = Creates lift for airplanes Intentional design of wing = Causes air to move faster over the wing Elasticity of air = Allows air to meet on the other side of the wing Lower pressure = Pulls the airplane up Signup and view all the answers

Match the following characteristics with their corresponding elements:

Curved more on the upper surface = Airplane wing Moves faster over the wing = Air Has lower pressure = Faster moving air Pulls the airplane up = Lower pressure Signup and view all the answers
