Forces in Elevators: Net Force 0 but No Weightlessness

[Matix Cubix]

Hi, I've been thinking about the forces in elevators where a gravitational field exisits, in the case where the elevator moves at a constant upward velocity, which means that there is an equal force to the total weight, meaning that the net force is 0, the thing that strikes me is that I still fell my weigth, and I'm not in a state of weightlessness, on the other hand, if I were in space on a space shuttle and I started the front and rear thrusters so that the thrust was equal , I would still be weightless, so it can not be an analogy to the elevator. Another thing, if I was in an elevator at a constant velocity, I feel that I am being accelerated, but of course I am not: If some one could answer my question I would be quite happy.

It is analogous to an elevator in free fall.

You are accelerated in the frame independent sense:

Oh, so could I say? that the force of gravity is a different that of a force when you get pushed? becuse in some sense in the gravity I wouldn't need to feel an acceleration, to knew that I am being accelerated towards a planet, but in the other case I would necessary need to feel an acceleration to knew that I am being accelerated, there is another case.,If I was in a disc moving with an angular speed, I would feel an acceleration, but this is just like the force when I get pushed. If my assumptions are correct, what happends with the other forces, like the electrical forces or the magnetic forces? Anyways thank you for your answer.
