So what's the bottom line with the "thrown watch" problem? Which clock is running faster, or are they both going at the same pace and reading the same time? Does it matter how fast the thrower throws the watch in the air or does it have to accelerate at exactly 9.8 m/s2. Does it matter how...

Wow you really cleared things up. I appreciate your detail because its really hard to grasp relativity from ALL frames of reference, especially non-inertial ones. Pretty sure I got it now, thanks.

sorry bout all the questions but i can finally sleep now...haha

ok that makes sense... thanks

Ahh. I see what you mean. Yea my confusion was definitely that I was assuming B's position to be static throughout the whole thing, and the answer lies in his motion while jumping. So to clear it up, when A and B hit the ground and meet up with C, all clocks WILL be ticking at the same rate but...

Thanks for responding. You're logic is what I had expected. Here's what I don't get though. How could B's clock continue to be ahead of A's (from C's perspective) if now, since they've jumped out and are standing right next to C, they're all seeing from the same perspective. In other words, A...

Please Help...Synchronized Clocks I've posted this before and I just want to clear things up. If A and B are on a train moving at a constant velocity (A in the front and B in the back) and they are asked to set their clocks to 12:00 when the light from a lightbulb in the center reaches them...

sorry to be a pain but i just want to understand it fully. I do fully understand the situation in which they jump out but not when the train just stops. thanks again.

I'm still a little unclear as to how it works out if they don't jump out and the train just stops like my initial question. Is it simply that one end is moving differently relative to the other, but even so, from C's perspective wouldn't the front obviously stop before the back which would...

Ahhh, thank you. that really cleared things up for me a lot. So if we go back and apply it to the train stopping instantly instead of them jumping out, does that mean that from C's perspective, he would see B (in the back) stop first?

Right but how could they remain out of sync if, according to A and B, they were never out of sync in the first place, so why should they be when they jump out simultaneously?

right that makes sense. But if the platform observer sees the front of the train stop first then that means that person B (in the back) will experience the time dilation slightly longer, which would only further deviate the two times, right?

It certainly helps to look at it that way, thanks. But I still have a little problem with your explanation. You say: What happens from C's point of view is that B's watch is a little ahead of A's, so B jumps out earlier than A. Why does B jump out earlier just cause his watch is ahead of...

I don't think that matters. It stops in everyone's frame of course, it just may be that person A and B perceive to stop at a different time than person C perceives it to stop, but the same question applies.

This is sort of a long post but I have to explain the following situation in order to ask the question so bare with me. Let's say two people, person A and person B, are on opposite ends of a train moving at a constant velocity and another observer is at rest on the platform outside (most of you...
