Reading Passage

Airplanes are very heavy, but they can rise into the sky. They fly because of forces that work on the plane while it moves through the air.

One important force is lift. Lift is made mostly by the wings. Airplane wings have a special shape. As air moves around the wing, the pressure above and below the wing changes. This helps push the wing upward.

For lift to happen, the airplane must move forward. Engines create thrust. Thrust pushes the airplane through the air. As the airplane moves faster, more air moves over the wings, and the wings can make enough lift.

Another force is drag. Drag pulls backward against the airplane. Engineers design airplanes to be smooth so they can reduce drag.

Gravity also affects the airplane. Gravity pulls the airplane downward. To fly, the airplane needs enough lift to balance or overcome gravity.

Pilots control the airplane with moving parts on the wings and tail. These parts help the plane turn, climb, and go down. Small changes in airflow can move a large airplane.

An airplane flies when thrust moves it forward, wings create lift, and the pilot controls its direction. Flying is not magic. It is the result of air, motion, shape, and careful design.

Lift, thrust, drag, and gravity are the main forces of airplane flight.

Key Vocabulary

Word	Meaning	Example
lift	an upward force that helps an airplane rise	The wings create lift.
thrust	a forward push that moves an airplane	Engines give the plane thrust.
drag	a force that slows something down in air or water	Smooth shapes reduce drag.
gravity	the force that pulls things toward Earth	Gravity pulls the airplane downward.
pressure	force from air or another substance pushing on something	Air pressure changes around the wing.

Reading Comprehension Questions

1. What force helps an airplane rise?
2. What part of the airplane makes most lift?
3. What creates thrust?
4. What does drag do?
5. Why does an airplane need enough lift?

Answers

1. Lift helps an airplane rise.
2. The wings make most of the lift.
3. Engines create thrust.
4. Drag slows the airplane down.
5. It needs enough lift to balance or overcome gravity.

Short Summary

Airplanes fly because engines create thrust and wings create lift. Lift works against gravity, while smooth design helps reduce drag.
