Air cannot do that alone. Airplane wings are shaped such that a forward motion will force them to lift.

What occurs if the air moves faster above an object than below it?
Faster-moving air exerts less pressure, so there will be force (lift) generated by the air below the object. This is the principle of powered heavier-than-air flight. The object will have a area of low(er) pressure in top than air underneath, causing lift. This is cause by the air on top being stretched out and having lower density or pressure then the bottom. If there is enough lift to counteract the weight of the object, the object will lift off the ground.
What causes lift?
lift is when air is blown at a moving object and the shape of the object pushes it down and itself up as an example when a plane moves down the runway, the air is pushed down by the shape of the wings
What is created when air currents dont meet up the right way after passing by an object?
What is created when air currents dont meet up the right way after passing an object? a) lift b) slope c) drag d) hydraulics A) LIFT is the answer
How can air resistance help the motion of an object?
Normally, air resistance slows an object and this does not help motion, it impedes it. Lift, which is an aerodynamic force, is very helpful and it's caused by air resistance. This allows a plane to lift off and stay in flight.
How much air pressure to lift a 1 kilo of object?
i will hurt is all i can say
Is there a real hovercraft?
Yes, they use high pressure air flow to lift the vehicles of the ground on a cusion of air.
How does something heavier than air stay off the ground?
lift
How do air balloons lift off from the ground?
Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
Why does the hot air balloon come down?
Once the air cools, the balloon will lose its lift and settle back to the ground.
How does a hot air balloon lift of the ground?
You have to trigger the heat, which goes through the tube and it heats the balloon and it flies in the air.
Why do paper aeroplanes fly in the air?
paper aeroplanes flies in air because they less resist the air. For example- if you drop a heavy object and a paper from same height, the heavy object reaches first to ground and the paper will reach ground after the object. Similarly, paper plane flies for some time in air then it comes down.
Why does a hot air balloon fly?
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.
