A plane is standing on a runway that can move (some sort of conveyer belt). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in opposite direction). The question is: Will the plane take off or not?

whats that supposed to mean?

would you care to elaborate. i am still unclear on your idea.

how about mounting the gun itself on a damper. this would be like one of those old guns we see in movies, when the gun fires, the barrel moves back a short distance with the damper absorbing the recoil.

as most of us know the conventional rail gun uses 2 rails and an armature to complete the circuit causing the 2 rails to repel and shoot the armature at very high velocities. whati want to know is why thishappend. the force is applied perpendicular to the rails and not parallel to it. why would a force that is acting perpendicular be able to force out the armature at such speeds. :confused:

just a thought but does the earths magnetosphere occur at ground level or some distance above?
