Richie:

On the subject of spinning up to an awesome frequency. Counter-question. What would be the weight of a body if it flew at 2nd space velocity within the Earth?

practically equal to its normal one, with a slight deviation, actually at high velocity mass changes, not weight.

I forgot to ask, how does this body move (trajectory of motion) relative to the Earth?
 
Another question. How do you create the "illusion" of moving at 2nd space speed? An "illusion" is when, from the point of view of physics, a body is moving, but from the point of view of an observer it is in place.

To make the observer move

Let's define "motion"
 
sanyooooook: almost equal to its normal, with a slight deviation, actually at higher speeds it's the mass that changes, not the weight.

Let's not bring up Uncle Einstein, Newton is enough for now :) The weight of a body depends on its speed. The trajectory is not worth bothering with either.

 
sergeev: Let's define "movement"
That's the point.

)), from what speed, remind me where does Newton say that? F=ma => m=F/a => a=F/m and also F=F

We can at most deduce from this that weight depends on changes in velocity, and therefore on changes in the force that is applied to the body.

Alexander, you have forgotten what 2nd space speed means :)
 
Start emitting light intensively :) preferably in one direction only.
