Lift acts against the force of gravity, pushing the aircraft up.
LIFT -- force provided by the wing and in perpendicular direction to the wing. In straight and level flight the lift is exactly equal to the aircraft weight. WEIGHT -- the force pulling vertically down on the airplane due to gravity. In straight and level flight this is equal to the lift. THRUST -- the force that pulls the airplane forward, provided by the propeller or jet engine. If the airplane is flying at a constant speed in level flight, this thrust is exactly equal to the drag. DRAG -- the aerodynamic force on the airplane in the opposite direction of its travel. Drag is due to skin friction, form drag (drag around wheels, struts, etc) and induced drag (produced by the wing as a side effect of lift)
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
Lift Gravity Thrust Drag Lift is the lifting force that allows airplanes to fly, gravity is the force pulling it back down. Thrust is the force that propels an airplane forward, drag is the aerodynamic friction slowing it down. These variables are constantly interacting with eachother, when an airplane is in straight and level flight, these forces are said to be in balance.

If the lift is greater than gravity then the airplane gains altitude.
lift, thrust, drag and weight(gravity)
LIFT -- force provided by the wing and in perpendicular direction to the wing. In straight and level flight the lift is exactly equal to the aircraft weight. WEIGHT -- the force pulling vertically down on the airplane due to gravity. In straight and level flight this is equal to the lift. THRUST -- the force that pulls the airplane forward, provided by the propeller or jet engine. If the airplane is flying at a constant speed in level flight, this thrust is exactly equal to the drag. DRAG -- the aerodynamic force on the airplane in the opposite direction of its travel. Drag is due to skin friction, form drag (drag around wheels, struts, etc) and induced drag (produced by the wing as a side effect of lift)
Essentially there are 4 aerodynamic forces that act on an airplane in flight; these are lift, drag, thrust and gravity (or weight).In simple terms, drag is the resistance of air (the backward force), thrust is the power of the airplane's engine (the forward force), lift is the upward force and gravity is the downward force. So for airplanes to fly, the thrust must be greater than the drag and the lift must be greater than the gravity (so as you can see, drag opposes thrust and lift opposes gravity).This is certainly the case when an airplane takes off or climbs. However, when it is in straight and level flight the opposing forces of lift and gravity are balanced. During a descent, gravity exceeds lift and to slow an airplane drag has to overcome thrust.

I think you might be referring to the four forces of flight. LIFT -- force provided by the wing and in perpendicular direction to the wing. In straight and level flight the lift is exactly equal to the aircraft weight. WEIGHT -- the force pulling vertically down on the airplane due to gravity. In straight and level flight this is equal to the lift. THRUST -- the force that pulls the airplane forward, provided by the propeller or jet engine. If the airplane is flying at a constant speed in level flight, this thrust is exactly equal to the drag. DRAG -- the aerodynamic force on the airplane in the opposite direction of its travel. Drag is due to skin friction, form drag (drag around wheels, struts, etc) and induced drag (produced by the wing as a side effect of lift)
Lift opposes gravity and drag opposes thrust. An airplane turns using a small amount of vertical lift vectored in a horizontal direction. gravity from below, the wind currents, atmospheric pressure and weight of the plane from above.
The peice of paper compares to the paper airplane because they both have the same mass. Whether a paper is flat,folded in half or is shaped into a fancy paper boat it will always have the same amount of mass.

Lift is the force that causes an airplane to rise. Lift is caused by the flowing of air under the wings. This causes the airplane to rise.
