A plane flies forwards by exerting a force on the air with its wings. the air pushes back on those wings with an equal force that propels the bird forwards
basically moving very fastly forward. it moves so fast that nothing can like stick or freeze to it. get it? thanx.
The engine starts it and the weight moves it
Wedge
An airplane stays up in the air due to a combination of factors. The main factor is the shape of the wings, which creates lift as air flows over and under them. The engines also provide thrust to move the plane forward, and the overall design of the plane helps maintain stability and control during flight.
If the frame of reference is the ground, and if you are running forward, you are indeed moving faster than the plane. If you are running toward the rear of the plane, you are moving slower than the plane.
The shape of the wing is such that when it moves forward the pressure on top is lower than on the bottom, thus air pressure pushes it upward ... as long as the plane moves fast enough.

The propulsion system of an aircraft moves the air backward. Air in turn pushes the aircraft forward. This is based on the Third Law of Newton.
Do not exceed the critical angle of attack, basically the angle the wings make with the oncoming air as the plane moves forward.
A plane is designed so that when it moves forward the air moving across its wings creates an upward force called lift, which counteracts the force of gravity.
thrust
The blades of propellers are angled (and shaped) to push large volumes of air back at high speeds. In an airplane, the air pushed by the propellers moves the plane forward by Newton's 3rd law (any force applied to an object causes an equal and opposite reaction - here the air goes back and the plane moves forward). The plane flies because the shape of the wings gives lift when they are pushed through the air at sufficient speed. In a helicopter, the air pushed by the propeller lifts the plane from the ground (still Newton's 3rd law). Helicopters require much bigger engines and propellers (per pound) than airplanes because the lift of wings is much more efficient than the brute force of the propeller. When helicopters move forward (backwards, sideways, etc.) it's because the propeller is tilted slightly causing some of the force to be applied backwards - which pushes the chopper forward.
The front of the main rotor is tilted down
Either drag (air resistance) slows the aircraft down, or lift (Bernoulli's principle) raises it up. When more air goes under the wing than over it, the aircraft "wants" to move up because objects favor movement into low pressure zones.
The turbines under the wings of the airplane suck air in, mix it with fuel, and then compress the air/fuel mixture. As the compressed mixture exits the engine, it burns hotly, creating a lot of thrust backwards, pushing the plane forward and overcoming drag. As the plane moves forward air moving over the wings and pushing up on the bottom creates lift to keep gravity from pulling the plane down. This happens throughout the whole flight of the plane. The continuous cycle of pushing air backwards with tremendous force and creating lift with the wings keeps the airplane up.
The 4 forces of air are: 1: thrust pushes the plane forward 2:drag pulls the plane backwards 3:gravity pulls the plane downwards 4:lift pulls the plane upwards
