How Can planes fly if there is gravity?

Planes do not actually defy gravity, though. Instead, the tilt and area of a plane’s wings manipulate the air particles around the plane, creating a strong enough lift that the force of gravity is overcome by the force of the air beneath the wings.

Do airplanes need gravity?

A plane must be built so that lift and thrust are stronger than the pull of gravity and drag by just the right amount. Lift from the wings is used to overcome the force of gravity. Shape is important in overcoming drag. For example, the nose of a plane is rounded so it can push through the air more easily.

What does airplane use as fuel?

kerosene
Aviation kerosene is the fuel of choice for aircraft across the globe.

What kind of plane does not need fuel?

No Propellers or Turbine Needed: MIT’s New Airplane Needs No Fuel or Moving Parts. Ever since the Wright Brothers launched their sustained flight of an aircraft, people have been ferried through the air in planes powered by moving parts—typically, a propellor or jet turbine.

How do airplanes fly answers?

Airplanes fly as a result of the forward force of thrust being greater than the backward force of drag. The upward force called lift is caused by a difference in air pressure above and below an airplane’s wings.

Why do paper airplanes fly?

Thrust and Lift Thrust is the forward movement of the plane. After this, paper airplanes are really gliders, converting altitude to forward motion. Lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down. It is this difference in pressure that enables the plane to fly.

Where is the fuel on a plane?

wings
Placement. On passenger planes, fuel tanks are often integrated into the wings, and when there are also tanks inside the body of the aircraft, the wing tanks are used preferentially. The placement reduces the stress on the wings during takeoff and flight, by putting the heavy fuel directly inside the source of lift.
