1. ### I Clock hypothesis, gravity time dilation and Equivalence Principle

Also, if acceleration can be decided just by the distance between endpoints, which is a result of different parts of the spring being at rest in different frames, then if we were to consider 3 balls connected with a simple string, giving no resistance, as in to consider this system an "object"...
2. ### I Clock hypothesis, gravity time dilation and Equivalence Principle

Maybe it isn't. I am currently in the process of figuring if measuring an object which does not have all its parts at rest within one frame is going to give me the proper results. I guess what i am looking for is the exact process to get the acceleration value a spring like accelerometer would...
3. ### I Clock hypothesis, gravity time dilation and Equivalence Principle

well yes, what i meant is that not every part of the spring is in the same rest frame but in a different one during the acceleration process.
4. ### I Clock hypothesis, gravity time dilation and Equivalence Principle

Is a spring with a mass attached to it a properly designed accelerometer? If yes, then which spring's part reference frame would you use to measure the contraction of the spring while it is under acceleration as the various parts aren't in the same frame during the acceleration process, or at...
5. ### I Clock hypothesis, gravity time dilation and Equivalence Principle

Ok, but how does one prove that? For example. If i imagine a spring with a mass on it, and consider this my accelerometer, then as i understand it, by design, this accelerometer works by checking the distance between the front and the back of the spring's body. For the accelerometer, the...
6. ### I Clock hypothesis, gravity time dilation and Equivalence Principle

I am puzzled myself about this. Einstein seems to have made a distinction between pairs of two cases. pair A) accelerating rocket with an observer inside and some observer on the surface of a planet "feeling gravity" (whatever feeling gravity means - a very unscientific expression IMO) pair...
7. ### Ball bouncing on a planet (no atmosphere) follow up questions

There is just one thing that puzzles me still. If we can look at this from any reference frame and both energy and momentum are to be conserved. How is momentum conserved when we look at the case where the ball just turned all it's kinetic energy into potential and is at it's highest point...
8. ### Ball bouncing on a planet (no atmosphere) follow up questions

Energy is never lost. The question is, if a ball hits another bigger ball (in this case, the planet) in an elastic collision, then does the smaller ball transfer some of it's energy to the bigger ball because of energy and momentum conservation? The answer to that, is yes I believe. It being an...
9. ### Ball bouncing on a planet (no atmosphere) follow up questions

So my next question. On the same planet with no atmosphere, the ball was bouncing on and came to a halt after some time, we now place a long, closed at the bottom, hollow cylinder/pipe, extending far into space. We are not concerned on if such a material to sustain the pipe without breaking...
10. ### Ball bouncing on a planet (no atmosphere) follow up questions

This is what I thought would happen as well. If no one objects to this after some time, I will continue with my follow up questions.
11. ### Ball bouncing on a planet (no atmosphere) follow up questions

This thread will contain several follow up questions, but let me start with the most simple one. Imagine a planet with no atmosphere and a ball in empty space. The ball is dropped on the planet from a certain height and starts bouncing. We ignore friction and consider this to be the fully...
12. ### Would this device(pic inside) work for boiling cold water?

This should be easy to confirm experimentally. Surely, if the earth's atmosphere pressure was less, such that it would be close to the boiling point of water at room temperature, it wouldn't make a difference to the experimental outcome as you describe it, I would think. So all we would need...
13. ### Would this device(pic inside) work for boiling cold water?

Maybe a better way to explain it by going macroscopic. Let's say we have a bunch of cannon balls with springs attached to them. Those cannon balls also have solar panels attached to them along with a pressure-meter. When the sun shines, the energy generated by the solar panels, is used to...
14. ### Would this device(pic inside) work for boiling cold water?

So you agree that if we thinned the atmosphere of earth to the point it would resemble the dome atmosphere, we could extract energy out of this system, but for the dome you believe that we would actually have to put more energy in into maintaining the vacuum or pressure to be more precise. Well...
15. ### Would this device(pic inside) work for boiling cold water?

The last part comes from experiments like this one In a vacuum water boils and turns into ice later. You end up with colder water if you somehow would extract the kinetic energy out of the steam, would you not? Or let me put it differently. If let's say our atmosphere was much thinner, to a...
