As the airplane lands, it loses forward momentum, and the pressure under the wings and the vacuum on top of the wings decrease. Hopefully the landing gear is down so its not a belly landing- if it was a belly landing, the momentum would be converted to heat by friction with the earth. Of course it does the same thing with the tires- but in a lot more controlable way

Stationary wheels first touch the ground. Because the runway meets the wheels off-centre (at the rim), the runway exerts a torque on the wheels, this causes the wheels to rotate.At first, the wheels are rotating too slowly and friction of the skidding wheels burns the tyres. This is why smoke is seen around the wheels just after landing. Pretty quickly, the wheels are rotating at the same rate as the ground is passing and the burning of the tyres stops (you hope!). Friction in the hubs and the braking mechanism (and aerodynamic drag) convert the aeroplane's kinetic energy to thermal energy ('Heat'). This process continues until all of the plane's kinetic energy is dissipated. Here, it stops.

The forward movement of the aircraft provides the lift on landing the aircraft is slowed by friction between the runway, wheels, wheel bearings, brakes and the aircraft's drag. Many aircraft have thrust reversal systems which either stop the thrust of the aircraft pushing it or actually direct it forward to provide engine braking. In terms of physics then momentum is converted to mainly heat. The runway, tyres and brakes are heated through friction. (brakes get very hot)

I'm not quite sure what you're asking.
The kinetic energy (the plane's forward motion) is absorbed by the runway creating friction which is expelled as heat. Also the plane brakes, which loses more energy to friction, again expelled as heat - slowing the plane down. That what you're asking?

I clench my teeth and my *** turns to jelly! The last thing I am thinking of is the physics and concept involved in the procedure!
