Question 1

What makes an airplane fly?

Accepted Answer

An airplane flies because air moves over and under its wings, creating lift. Lift helps the airplane go up into the sky.

Question 2

What is lift?

Accepted Answer

Lift is the force that pushes the airplane up. Wings are shaped to make the air move faster on top and slower underneath, creating lift.

Question 3

How do engines help planes fly?

Accepted Answer

Engines push the airplane forward through the air. This forward motion helps the wings create lift to take off and stay in the sky.

Question 4

Why do airplanes need wings?

Accepted Answer

Wings help planes lift off the ground and stay up in the air. They catch and shape the wind to create the lift needed for flying.

Question 5

What happens if a plane goes too slow?

Accepted Answer

If a plane goes too slow, it might not have enough lift to stay in the air. This can cause the plane to descend or even stop flying, which is called stalling.

Question 6

How do pilots control airplanes?

Accepted Answer

Pilots use controls in the cockpit to move the plane's parts like the rudders, ailerons, and elevators. These parts help steer the plane up, down, and side to side.

Question 7

What is thrust?

Accepted Answer

Thrust is the force that moves the airplane forward. Engines provide thrust to help the plane speed up and lift off the ground.

Question 8

Why do airplanes have tails?

Accepted Answer

Tails help planes stay steady and balanced while flying. They make it easier to control which direction the plane is going.

Question 9

What is drag?

Accepted Answer

Drag is the force that slows the airplane down. It's like the air pushing back against the plane as it moves forward.

Question 10

Why are planes shaped like they are?

Accepted Answer

Planes are shaped to move smoothly through the air, which reduces drag. Their streamlined design helps them go faster and use less energy.

Question 11

What keeps an airplane from falling out of the sky?

Accepted Answer

Lift from the wings and thrust from the engines keep an airplane in the sky. Lift pushes it up, while thrust moves it forward.

Question 12

Why does a plane need a runway?

Accepted Answer

Planes need a runway to gain enough speed for takeoff. The runway is a straight path that helps planes go fast enough to lift into the air.

Question 13

What happens during takeoff?

Accepted Answer

During takeoff, a plane speeds along the runway until it builds up enough lift. Once there is enough lift, the plane rises into the sky.

Question 14

What happens during landing?

Accepted Answer

During landing, the plane slows down and aligns with the runway. The pilot lowers the plane gently until the wheels touch the ground safely.

Question 15

How do planes stay on course?

Accepted Answer

Planes use navigation tools and systems to follow a planned path. Pilots and computers check the course to make sure the plane is going the right way.

Question 16

What are the four main forces acting on a plane?

Accepted Answer

The four main forces are lift, weight, thrust, and drag. Lift pushes up, weight pulls down, thrust moves forward, and drag slows down.

Question 17

How do airplanes turn in the air?

Accepted Answer

Airplanes turn by tilting their wings or using the tail rudder. This changes the direction of lift and helps the plane make turns.

Question 18

Do planes fly higher than birds?

Accepted Answer

Yes, planes often fly much higher than birds. They can fly in the sky thousands of feet above the ground, where birds usually don't go.

Question 19

What is turbulence?

Accepted Answer

Turbulence is when the air gets bumpy, causing the plane to shake a bit. It's like driving on a rocky road in the sky.

Question 20

Can planes fly in any weather?

Accepted Answer

Planes can fly in most weather, but they avoid dangerous storms or harsh conditions. Pilots and airports check the weather to make sure it's safe to fly.
