How do planes fly if gravity pulls everything to the centre of the earth?

The air flowing over the aerofoil shape of the wings creates lift. The upper surface of the wing is longer than the under surface. This creates a pressure difference and the wing moves upwards to try to equalize these pressures. When the lifting force is greater than the weight of the plane plus gravity trying to keep it on the ground it lifts off. Also the angle of attack into the wind during take off also acts in the same way that a moving surfboard keeps the surfer skimming on the surface of the ocean but as soon as he slows down he sinks.

How much is the gravity at the center of the earth and in which direction is it pulling?
The gravity at the centre of the Earth (due to the Eath's mass) is Zero.
Value of accelaration due to gravity at the centre of the earth?
Zero.
What is the name of the force pulling us to the centre of the Earth?
gravity
What is the name of a force that pulls object towards the centre of the earth?
gravity
How weight can change?
As the mass of a body or things is constant , the weight only depends on the the gravity 'g'. As the gravity increases with the decrease of the hight of the mass from the centre of the earth , the mass also increases with the decrease of hight from the centre of the earth.
What is meant by center of gravity?
gravity is the force that pulls everything down towards the centre of the earth.
Does gravity attract things towards the surface of the earth?
Gravity attracts things toward the core, or centre, of the Earth, that's how everything is able to stay on the surface.
Why are the most dense materials the bottom layer in the earth?
Gravity !... Gravity draws everything towards the centre of the Earth - therefore the heaviest materials are closer to the core.
What force are you working against when you lift a backpack?
gravity, it is the force that pulls everything towards the centre of the earth.
What forces are you working against when you lift a backpack?
gravity, it is the force that pulls everything towards the centre of the earth.
What lies at the centre of gravity and earth?
The Earth's Core lies at the centre.
Is earth's gravity the same on the surface as it is in the center of the earth?
No. At the centre of the earth the acceleration due to gravity is ZERO
What would happen to your head if it was at the center of the earth?
It, and everything inside it, would be crushed (this is, of course, if the centre of the Earth was empty, because if it wasn't, then you would be burnt to a crisp due to the immense heat fo the centre of the Earth). Your head would be crushed because gravity pulls you to the centre of the Earth, and if this is happening all over the Earth, then loads of gravity is going into one spot in the centre of the Earth. This would all push at you on all sides and subsequently crush you.
Where is the earths gravity the greatest?
At the centre of the Earth.
Why does water flow downward?
Gravity Gravity is the force that pulls everything downwards towards the centre of the earth. There are no scientific explanations to why and how this force works - it's God's perfect design.
Where does the centre of gravity of the atmosphere of the earth lie?
It lies at the center of the Earth.
Where does the centre of gravity of atmosphere of earth lie?
It lies at the center of the Earth.
