Question 1

What is flight?

Accepted Answer

Flight is when something moves through the air, like birds and airplanes. It's when you go up in the sky and stay there without falling back down right away!

Question 2

How do planes stay in the air?

Accepted Answer

Planes stay in the air because of something called lift. The wings of the plane push air down, and this helps push the plane up!

Question 3

What are the main forces involved in flight?

Accepted Answer

The main forces are lift, weight, thrust, and drag. Lift helps the plane go up, weight pulls it down, thrust makes it go forward, and drag slows it down.

Question 4

What is lift?

Accepted Answer

Lift is a force that pushes things up into the air. It's what helps birds and planes fly high above the ground.

Question 5

What is thrust?

Accepted Answer

Thrust is the force that pushes planes forward through the air. It's like when you push a shopping cart to make it move!

Question 6

Why don’t planes fall out of the sky?

Accepted Answer

Planes don't fall because the wings create lift and the engines create thrust, which help them stay up in the air. They are balanced so they can fly smoothly.

Question 7

What are engines?

Accepted Answer

Engines are machines that make things move. In airplanes, engines help make thrust, pushing the plane forward.

Question 8

How do birds fly?

Accepted Answer

Birds fly by flapping their wings to create lift and thrust. Their wing shape helps them glide through the air, just like a paper airplane!

Question 9

What is drag?

Accepted Answer

Drag is a force that slows things down when they try to move through the air. It's like when wind pushes against you when you’re riding a bike!

Question 10

What is weight in flight?

Accepted Answer

Weight is the force of gravity that pulls things down to the ground. In flight, it works against lift trying to pull the plane back down.

Question 11

How do helicopters fly?

Accepted Answer

Helicopters fly using big spinning blades on top, called rotors, to create lift. The spinning makes the air move down and pushes the helicopter up!

Question 12

Why do planes have wings?

Accepted Answer

Planes have wings to help them create lift. The wings catch the air and work like the wings of a bird to keep them in the sky.

Question 13

What technology helps us fly better?

Accepted Answer

Technology like GPS helps pilots know where they are going, and computers help pilots fly safely. Special materials also make planes lighter and faster!

Question 14

Why do some airplanes have jet engines?

Accepted Answer

Jet engines are powerful and can push the airplane very fast through the sky. They are great for flying long distances quickly!

Question 15

What's the cockpit in an airplane?

Accepted Answer

The cockpit is where the pilot sits and controls the airplane. It's full of dials, buttons, and screens so pilots know how the plane is doing.

Question 16

What do pilots do?

Accepted Answer

Pilots fly the airplane. They make sure the airplane goes in the right direction and stays safe, just like a driver does with a car.

Question 17

How does the shape of wings help in flying?

Accepted Answer

The shape of wings helps lift the plane because they are curved on top and flat on the bottom. This makes the air move faster over the top, lifting the plane up.

Question 18

What are flaps on an airplane?

Accepted Answer

Flaps are parts of the wings that pilots can move to change the shape of the wing. They help the airplane slow down and land smoothly.

Question 19

Why does a plane need a runway to take off and land?

Accepted Answer

A runway gives the plane a straight, clear path to get enough speed to lift off and enough space to slow down and stop when landing.

Question 20

What is a paper airplane and how does it fly?

Accepted Answer

A paper airplane is a small model made out of paper that flies when thrown. It uses simple lift and drag, just like a real airplane, to glide through the air.
