Chapter 1
How Airplanes Stay Aloft
Why Four Forces Keep an Airplane Up
An airplane flies because four forces work together: lift, thrust, drag, and weight. Lift pushes up. Weight pulls down. Thrust moves the airplane forward. Drag pushes against its motion.
Fun fact: A paper airplane can fly without an engine because your throw gives it thrust! Its wings use moving air to make lift, like a bird’s wings.
When lift and thrust work well, the plane can stay in the air. If weight or drag becomes stronger, the plane may drop or slow down. You can see these forces with a simple paper test.
See the Forces in Action
Materials: one sheet of paper, a pencil, a ruler, and a safe open space Time: 10 minutes
Quick example: Hold the paper flat. Blow across its top. The paper may lift a little. Moving air can help create lift.
Your Turn
1. Fold the paper in half lengthwise. Open it again. 2. Hold the short edges and gently bend the paper into a shallow curve. 3. Place the curved paper on your palm. 4. Walk forward slowly while holding it level. Your movement gives it thrust. 5. Notice the air pushing on the paper. This is part of drag. 6. Let go. Watch whether the paper rises, stays level, or falls. Weight pulls it down. 7. Draw the paper’s path here: __________________________ 8. Circle one: The paper went up / level / down.
Great job if you named all four forces and drew the paper’s path!
Change the Test
Use different paper colours. Test a red sheet and a blue sheet. Write which one flew farther: ____________________.
Try the same paper with a faster walk. Circle one: more lift / less lift / no change.
Work with a friend. One child holds the paper, and the other gently blows across the top. Switch places after one try.
Check and Create
Circle Yes or No.
1. Does lift push an airplane up? Yes / No 2. Does weight pull an airplane down? Yes / No 3. Does thrust move an airplane forward? Yes / No 4. Does drag help an airplane speed up? Yes / No
Draw arrows on a paper airplane: draw one arrow up for lift, one down for weight, one forward for thrust, and one backward for drag.
Give yourself a ★ if you drew all four arrows.
Now make a tiny paper plane and test it. Which force seemed strongest during its flight? Draw that force as a big arrow.
