During landing, the purpose is to slow down the aircraft's ground speed as slow as you can without it stalling. You want to maintain Lift, not necessarily get more lift. At higher speeds, the aircraft has plenty of Lift. However during landing, the speed is slower and the angle of attack is increased to provide more Lift at lower speeds.
On earth, 490N or more is required to lift 50kg
it makes the lift increase a lot but is slow the plane down a lot as well that is why the pilots like me use is when we are landing a plane.
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

The wings give the aircraft 'lift' especially when it is at a slower speed such as landing
They help produce more lift by the wing. Lift is dependant on the formula L=CL x1/2densityx speed (squared) xsurface area So the greater the surface area the more lift produced. Flaps can extend from the front of the back of the wing. They also change the curvature of the wing thus producing more lift as well. They are used for takeoff and landing because they allow the wing to produce more lift at a slower speed.
lift and thrust
They give extra lift on take-off and landing.
The airplane develops lift through the process of moving a mass of air over the wings at a sufficient rate ... the more mass per second, the more lift. The density of air is less at high altitudes, meaning any given volume has less mass than the same volume would have at lower altitude. In order to blow the required amount of mass (per second) over the wings and develop the required lift, more speed is required, hence a longer runway over which to accelerate.

There shall be a floor or landing on each side of each exterior door. Exception: Where a stairway of two or fewer risers is located on the exterior side of a door, other than the required exit door, a landing is not required for the exterior side of the door. The floor or landing at a door shall not be more than 1 1/2 inches (38 mm) lower than that top of the threshold. Exception: Provided that the exterior doorway is not for the exit door required by Section R311, the step between the landing at an exterior doorway and the top of the threshold shall have a rise not greater than permitted in Section R314.2. The door, other than an exterior storm or screen door, shall not swing over the landing.
Landing
They are useful for takeoff to get lift and at landing for slowing down the plane.
The flaps help to increase lift, which is essential to the landing and takeoff phase[s].
