Introduction
Airplanes weighing hundreds of tons soar through the sky every day. But how do they fly? The secret is physics—lift, thrust, and aerodynamics.
The Four Forces of Flight
- Lift: Upward force generated by wings.
- Thrust: Engine power pushing forward.
- Drag: Air resistance opposing motion.
- Weight: Gravity pulling downward.
The Bernoulli Principle
Air moving faster over the curved top of the wing creates lower pressure than below, lifting the plane into the air.
Fun Fact
A Boeing 747 generates enough lift to carry 400+ people across continents!
