How do aero planes stay in the air?

Just look at the birds that fly high in the sky. And the human beings have made it possible through airplanes, helicopters etc. But have you ever thought that how the airplanes stay in air.

 The reason is that there are 4 types of forces that act with the airplane when it is in the air and the 4 forces are thrust, gravity, lift and drag. So from these forces the lift force helps the airplanes to move upwards and stay in the air. So to do it the lift force should be more the force of the gravity or else the airplane wouldn’t fly..

Talking about the thrust force, it should be more than the drag force (force by the moving food restricting the airplane to go forward) that helps the airplane to move in the air frontwards and other directions. This force is made by the jet engine.

So to lift the airplane and increase the lift force the airplane has wings which are curved from the top and flat from the base. This shape is known as an aero foil. And when the air hits the upper part the air diverts and moves upwards in a straight line but because of the curved shape the air is pulled and it moves around .Then the air is stretched at a high volume which result of dropping the pressure but at the opposite sides means at the under of the wing the pressure becomes high and get increased.

So as the air speed up and accelerate under the wing and goes down creating a lift force upwards and moving the airplane upwards.

Air goes down-Plane goes up

Air goes backwards-Plane move frontwards

Why Moon Appears Shiny in night

WHY MOON APPEARS SHINY IN THE NIGHT?   Does the moon have its own light or not? At night we all see a shiny round thing in the sky which appears in different shapes every day. Do you know what it is? It is the moon. The moon is the shiniest thing in the sky during night and many people think that it has its own light. But it is wrong. The moon does not have its own light like the bulb, lamp or sun. From all the celestial bodies in the space there are only the stars which have their own light. Even planets also do not have their own light. From the earth our eyes perceive that moon must have its own light but the reality is quite different. The rays of sun that fall on moon undergo reflection and when the reflected rays reach our eyes we are able to see the moon and perceive that moon is shining. The same is responsible for the different shapes that the moon acquires. The phases of moon are in being due to variation of the area on which the light is falling. The area of the ...
