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 scientific principle of lift generation?Bernoulli's principle and Newton's third law of motion
2. What is the four fundamental forces of flight?Lift, Drag, Thrust, and Weight
3. How did the Wright brothers start flying?Orville and Wilbur Wright built the Wright Flyer, a small biplane, and on December 17, 1903, it flew for 12 seconds and 120 feet. Their careful study of aerodynamics and wing warping made the flight possible.
4. Why do airplane wings look curved on top?The curved top of a wing makes air travel faster over it, lowering the pressure and creating lift. This is explained by Bernoulli’s principle.

Airfoil: The specific cross-sectional shape of a wing, designed to generate aerodynamic forces, primarily lift.
Bernoulli's Principle: A physics principle stating that an increase in the speed of a fluid (like air) occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.
Drag: The aerodynamic force that opposes the motion of an aircraft through the air.
Thrust: The force generated by the aircraft's engines that propels it forward.
