The forces acting on an aircraft during any phase of flight: thrust, drag, lift, and weight.
a hard landing
Almost every aspect of an airplane landing is managed by computer. The most important aspect is decelerating the airplane so the brakes and landing gear can stop the plane.
landing the airplane
The pilot and the co-pilot are responsible for landing the airplane.

Forces, these forces can be created by the environment or the airplane.
Depends on the speed of the airplane and the landing delays.
There are two forces that causes an airplane to be airborne. They are Thrust and Lift. The other two forces resists the airplane's flight. They are Gravity and Drag.
the forces are equal to balance the aircraft in flight
vertical loads, longitudinal loads and vertical loads
Gravity, force and lift are all forces that cause an airplane to fly. There are more forces depending on what time of airplane is in flight. For example the forces used to keep a comerical jet as to a fighter or military jet. As there are many forces the same the proportion is different there for the air flow if different on each airplane.
To avoid accidents when the airplane is landing.
