what is the feature that lift both birds and planes?

Answer 1

The wings. The wing is shaped with the upper portion slightly curved up and gently slopes down and back so that the air moving over the wing on top is moving slower than the air moving under the wing. The faster moving air pushes upward, creating lift and lifting up the plane or bird.

Answer 2

Lift vs. drag, that's where if the air that passes over the wing goes slower than the air under the wing the bird or plane will rise. But its a little more complicated to explain. And each example provides thrust in different ways.

Answer 3

The secret lies in the cross-section. All wings are shapped like a "D" on it's side (rotated 90 degrees counter-clockwise). When air goes around it, it travels a longer distance on the top than the bottom. Due to the homogenous nature of the air, this creates a system of lower air pressure at the top, relative to the bottom, and this creates lift!

Answer 4

The difference in air pressure above and below the wing. Creates lift.

Answer 5

the feature would be the wings. the wings create greater upwards force(lift) than drag force to lift the plane or bird.

Answer 6

Deferences in air pressure above and below the wings, there is more air pressure below the wings so that air is going to lift the plane.

Answer 7

A combination of air under and over their wings which creates lift !

Answer 8

the wing, which creates lift and drag
