Your post was gibberish so yes it does.
Maybe you meant momentum equals mass times deceleration then?
You certainly seemed to claim that a rocket gets to escape velocity by slowing down...
No. My post was quite clear and meant nothing like that.
I explained it quite clearly, the 11.1 km/s is the escape velocity from the surface of Earth.
This is based upon gravity not being able to stop it and pull it back to Earth.
Escape velocity is simply the velocity at which the acceleration of gravity is just unable to stop it, such that if the only objects in the universe where Earth (or whatever planet/mass) and the probe in question, the probe will slow down and approach a velocity of 0 as it got infinitely far away from Earth.
If the velocity is higher than escape velocity, instead of approaching a velocity of 0 it will approach some finite velocity indicative of the excess velocity it has.
As many people know, if you throw something up, it slows down as gravity accelerates it towards Earth (i.e. down).
The same thing happens with space probes and powered rockets, and the Tesla.
If an object starts with an escape velocity and no force other than gravity acts upon it, it will still be at escape velocity, even as its velocity tends to 0 (or whatever finite velocity it will tend to) as the distance tends to infinity.
This means that as you move further from the centre of Earth, with gravity slowing you down as you do, the escape velocity for that distance decreases.
Notice how this is nothing like what you are presenting it as?
