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?

Another question. How do you create the "illusion" of moving at 2nd space velocity? An "illusion" is when, from the point of view of physics, the body is moving, but from the point of view of the observer it is in place.

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.

)), 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.
