Understanding the Forces That Enable Airplane Flight: Test Your Knowledge!

Explore the fundamental forces of flight: weight, drag, lift, and thrust. Discover how Newton's Third Law relates to aviation, where every action has an equal and opposite reaction. Learn how thrust produced by jet engines propels airplanes forward, how drag counteracts this movement, and how lift is generated by air pressure differences over the wings. Test your understanding by matching terms to their definitions! Strengthen your knowledge of the principles that allow airplanes to soar through the sky.

  1. What Causes an Airplane to Fly?

  2. Test Your Knowledge ! Match term with letter. Weight Drag Lift Thrust A_______ B________ C________ D________

  3. Newton’s Third Law • For every action there is an equal and opposite reaction. • What does this have to do with flight?

  4. Thrust • The goal of a jet engine is to produce thrust. The engine pushes air molecules out the exhaust end of the turbine to generate a high speed jet of exhaust gas. THRUST!

  5. Thrust from the engine moves the airplane forward.

  6. Drag • As the plane moves forward the air around it creates a force called Drag. • Drag resists the movement of the airplane.

  7. Lift • How does an airplane create lift? • We can look to our fine feathered friends for the answer

  8. Lift • Air moves faster over the wing than underneath it. • Because faster air exerts less pressure than slower moving air………………………..

  9. Lift • ……………....The pressure underneath the wings lifts the plane off the ground

  10. Flight • To stay in level flight the following relationships must be true; • A) Lift = C) Weight • B) Thrust = D) Drag
