how plane can fly?

 Nama: Rindu Maharani

Class: 11.11

Draft 1 

Thesis: How plane can fly? 

Explanation sequences: 

Now, almost every day we see planes flying above. Inside, there are hundreds of people sitting, walking, and even running. Have you ever wondered why such a heavy metal object can float so freely in the air? How can airplanes fly like birds?

Do you know that airplanes can generate energy? That is why this object can fly, because of the force. Such a force, scientifically called a Lift, can move an airplane upward. How come?

There are mainly four forces that contribute to flying an airplane. They are Weight, Thrust, Drag, and Lift. How do those work? First, to move an airplane forward, the Thrust created by the engines must be greater than the force produced by the air resistance called Drag.

Second, to move the airplane upward, it needs enough forward motion. The airplane can only fly if the force of Lift is much greater than in Weight. This process can push an airplane to fly. 

conclusion: 

So, the conclusion is planes have engines to help propel them. Air will flow quickly through the wings, creating a thrust force that is much greater than the drag force.
