Example of Explanation Text - How a Plane Flies

Today, Everyone must see a plane flying. Even Some of the people have flown with an airplane. Have you ever thought why this heavy metal object can be lifted in the air? How can the airplane fly?

An airplane flies because it can generate a force. The force is scientifically called Lift. It normally moves that heavy airplane upward. So, how does the Lift happen? Well. Lift occurs by the generating of the forward motion of the airplane through the air. please note that this motion of the airplane is produced by what we call the Thrust of the engines.
Example of explanation text - How airplane flies

There are four forces which act on a flying airplane. They are Thrust, Lift , Drag and Weight. How do these four forces work? When the Thrust which is produced by the engines is greater than the force of Drag which is produced by the resistance of the air, the airplane will moves forward. When the forward motion is enough to produce a force of Lift which is greater than the force of Weight, the airplane will moves upward.
