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:

<p>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</p> Signup and view all the answers

Match the following terms with their definitions:

<p>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</p> Signup and view all the answers

Match the following phenomena with their causes:

<p>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</p> Signup and view all the answers

Match the following terms with their effects:

<p>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</p> Signup and view all the answers

Match the following characteristics with their corresponding elements:

<p>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</p> Signup and view all the answers
