Does spinning a massive sphere at high speed would somehow create extra gravity pull (or some sort of phenomenon perceived as such) added to it's initial gravity force (rest state gravity/not spinning state gravity)?
I came to the assumption that accelerating the speed of an object would...
Thank you, both of you confirmed what I suspected and needed to know as for in ideal situation as first describe and also in not so ideal situation.
As for "why in space?" it is because I wanted to take gravity out of the equation. You are right that a normal Newton pendulum would need...
After having read the FAQ subforum, I still have hard time conceiving certain ideas which still are not clear to me. Especially about the "Rest frame of a photon"
While understanding every word of that post, it failed to help me confirm or reject my understanding of some ideas:
"In the rest...
Someone told me that due to thermodynamic, the perpetual motion will come to an end. Is it correct?
If so, how could the energy be released at all? It is not as if it would be emitting heat or radiation. At least not significantly no?
I was wondering what will happen if we had a Newton's pendulum (cradle ) in space out of any significant gravitational orbit, although one with only two balls where the string attached to each balls would only be tied to the same center.
This pendulum would allow the first ball to hit the...
Knowing that a photon can not be at rest, I was wondering what would happen supposing if we travel at the same constant speed as light in parallel or in front of a specific ray of light.
Would that ray of light seems to be still for us?
Would the momentum mass of the photons of that...
