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.
What else can I help you with?
Do planes have gravity?
Planes are subject to the force of gravity just like any other object on Earth. Gravity is what keeps planes and other objects anchored to the ground, and it also affects their movement and flight. Pilots use gravity to control the descent and ascent of a plane, as well as to maintain stability during flight.
What is the name of a force that pulls object towards the centre of the earth?
The force that pulls objects towards the center of the Earth is called gravity.
Can you pull the gravity upward to make material move?
The Newtons theory of Gravitational Forces would apply. ---------------------------------------------------------------- However you cannot change the downward direction of gravity on Earth. Everything is being pulled towards the centre of the Earth. It is true, however that the gravitational pull is strongest at the Earth's surface, and the pull is less atop a mountain or down a deep shaft of a mine.
Why don't we fall if the Earth is round?
We don't fall off the Earth because of gravity. Gravity is a force that pulls everything towards the center of the Earth, keeping us and everything else on the surface. The Earth's round shape allows gravity to act evenly in all directions, keeping us grounded.
Where does gravity pull everything towards?
Gravity pulls everything towards the center of mass of an object. For example, on Earth, gravity pulls objects towards the center of the planet.
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
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 is the earths gravity the greatest?
At the centre of the Earth.
