Lift pushes the airplane up. The way air moves around the wings gives the airplane lift. The shape of the wings helps with lift, too.

Do planes have gravity?
Planes are pulled down by gravity, just like everything else. But at the same time, they're wings are being pushed up by air pressure, so the forces balance out and they stay up in the air.
What do radar signals pick up?
land vehicles, and air machines such as cars, planes etc.
How do planes stay in the air and keep flying?
Because the air-pressure under their Wings is greater than the air-pressure above their Wings. See the aero-foil.
What are the four forces that act on planes?
Lift (up)Thrust (forward)Gravity (down)Drag (backward)
How do you harness elastic energy?
Think of any machine that uses a Wind Up motor. E.g., a wind up watch or clock, wind up toys. Then there are rubber band powered air planes.
How are planes different from 1903 to now?
They can stay up longer, fly faster and further, and are usually much bigger.

What are arthur Weasley's desires?
To collect plugs, tinker with muggle artifacts and most importantly: to find out how planes stay up.
What is the force that enables planes to stay in the air?
Lift
How can a submarine stay submerged at certain depth underwater?
The military submarines maintain depth by use of the planes. As they move through the water, a little up or down "tilt" on the planes will keep the boat at the correct depth.
What layer of the atmosphere has planes in it?
Planes can go up to the STRATOSPHERE.
Why planes fly in different heights?
They have to stay away from other planes so flying at different heights gives them room. Several can be "stacked".
It is a space figure make up of planes?
Not necessarily. A sphere is a "space" figure, but is not made up of planes.
Are inclined planes straight up and down?
no they are leaning which is why they are called inclined planes
How do planes stay in the sky?
because the airfoil shape makes tiny air molecules at the bottom slow down and the top speed up. The engine just pushes the plane.
How are planes different than helicopters?
Planes cannot land straight up and down
How do people come up with planes?
Planes come up on their own, with the help of pilots, fuel and good design. The people are on board for the ride.
