Lift
increases with speed
I believe it is levitation you mean by levity. The gravity is the acceleration to centre of planet while levitation is the force act against and nullify gravitation. Levitation may come by many form such as magnetic force or suspension in gas or liquid stream. Floating in water is considered a levitation by buoyancy force.
The force that keeps objects floating is called buoyancy. It is the upward force exerted by a fluid that opposes the weight of an immersed object.
Lift: The force that keeps the plane flying.Drag: The force that slows down the plane. Weight: Theattractionto the ground.
The plane that carries the President of the United States of America is always called Air Force One. ANY plane he transfers to adopts the name while the President is on board, while all other planes he had been on revert to their standard 'name' (such as a '747').
The force that keeps an object moving is called inertia. Inertia is an object's resistance to changes in its motion and is related to its mass.
its called gravity
In level steady flight, lift force equals weight, and thrust force equals drag force. This balance of forces keeps the airplane in level flight without ascending or descending.
That force is called gravity.

The force that keeps us on Earth is called gravity. It is the force of attraction between objects with mass, such as the Earth and everything on its surface.
