How does a jet-engine compressor compress air?

[Danger]

That's squarely in Fred's arena, but I don't think so. There are a lot of variables that contribute to creating thrust, such as type of fuel, combustion temperature, nozzle design, exhaust temperature...

 

[FredGarvin]

Theoretically, the most basic equation for thrust is

$$F_t= \dot{m}(V_{OUT}-V_{IN})$$

where
$$\dot{m}$$ = air mass flow rate
$$V_{OUT}$$ = air exit velocity
$$V_{IN}$$ = air inlet velocity

1.ooohhhh i thought thrust= exhaust velocity * rate of combustion
is this wrong?

2.which part of the aircraft experiences this reaction force(thrust) first? (is this question stupid?)
3.is there a difference between thrust and propulsion?
4.and for compression?
there's no theoretical equation for compression?
