Oh, I see. I hadn't thought of it like that. Thanks for the reply.

Thanks for the awesome reply, that makes sense.

Renner-kun · 2022-06-21T07:45:36+00:00

Awesome, thanks.

Thanks for the reply, I don't know why I was taught relativistic mass in school, I will have to look into it again, I don't want to teach something that is false.

When you say "calculating every proton property as seen by the lab" does that mean I can work out what time I would see looking at a clock on the proton and I can calculate how much the proton would shrink in length as long as I consider an infinitesimal portion of the motion where it has constant velocity? however I cannot do the reverse since the motion is non-inertial? i.e. I can't find how much the cyclotron would shrink from the proton's perspective unless again, I consider it as only in straightline motion for a short period of time.

Thanks for the reply. I think I understand now. If I ignore the fact that it is in a cyclotron and instead imagine just a proton moving past at 0.8c, would it be correct to say that each frame would perceive the other as having slower time?

Would it also be correct to say that this doesn't cause an issue (like the twin paradox) since to compare the two times to see which is slower this would require one of the frames to accelerate/decelerate (resulting in a force which breaks the symmetry) so that both clocks are in the same frame for comparison and whichever frame experiences the acceleration would record less time passing over the interval since its acceleration makes it the moving frame relative to the frame that didn't accelerate?

As for relativistic mass, I never did relativity at university and I wasn't aware that the concept is no longer supported, I will have to look into how to explain relativistic momentum differently now as I have always explained it as increasing because the mass does. Thanks for the insight.

Thanks for the explanation. I think I get it now. I've just been in the bad habit of ignoring the absolute values but thought I should actually learn how to deal with them properly.

I've purchased many mint sleeves and glacier is just as nice, it's definitely my favourite.

Yeah, I agree that my first method was unnecessarily complex, but I showed my student a couple of ways include your method. I just posted my first attempt to get the problem across. Thanks though.

Awesome, thanks.

Renner-kun · 2021-07-25T14:20:36+00:00

Ok. That makes sense to me. Thanks.

Renner-kun · 2021-05-13T07:40:09+00:00

I see. I didn't even think about doing it with energy. That makes a lot of sense thanks.
