Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the governing principles?Newton's laws of motion and fluid dynamics principles
2. What is the key theorist?Ludwig Prandtl developed the boundary layer theory
3. How does a wing make a plane go up?A wing is shaped so that air moves faster over the top than the bottom, creating lower pressure above the wing and higher pressure below, which pushes the plane upward.
4. What is drag and why does it slow things down?Drag is a force that goes against the direction of motion, caused by friction and the shape of the object, and it makes planes and cars slow down.

Boundary Layer: The thin layer of fluid close to a solid surface where viscous effects are significant.
Compressibility: The tendency of a fluid to change its volume and density under pressure changes.
Reynolds Number: A dimensionless quantity used to predict flow patterns in different fluid flow situations.
