wow... so if someone in the ship were somehow able to instantaneously observe light, they would observe that the light hit the station's front sensor first, then the ships two sensors, then the stations back sensor(and someone in the station would observe everything i just said, with the words...
god, there's a lot of background i don't have (and i still can't get over the whole "they both observe each other as aging slower" thing!), but this is starting to make more sense to me, especially after reading some of the article in that link(which is really helpful, thanks!). i just finished...
that can't be possible, can it? let's say you had two sensors attached to the spaceship, one out a mile in front of the ship and one out a mile in the back (imagine long mic booms sticking off the front and back), and you had two more sensors attached to the station in a similar fasion, and...
woops, i meant to say that the ship was moving half the speed of light in the first example. in the second example, i was interested mostly in the time dilation, though i think that makes more sense to me now, after reading warren's post in another thread... so now i have a question that has...
huh?? wow, that throws a wrench in the gears :P so if two people have a great difference in velocity, they'll both observe the other person as aging less over time then themselves? maybe that explains a few of the things i haven't gotten so far... what about the time difference when they...
oh ok, that goes along with my current (limited) understanding of things. so what determines who's clock goes slower and who's goes faster when talking about time dilation?
there are a few things i don't get when it comes to light moving at c from all frames of reference... i mean it makes sense to me in some cases: like if an observer on the Earth sees a missle going one way at half the speed of light, and a spaceship going the other way at the speed of light, the...
man, i see a lot of symbols i don't recognize (like the upper case beta and the trig functions with the 'h' on the end), but i think i get the jist of it. at the very least, i know that the answer to my question is yes :D thanks for the responses guys
Kinetic energy is 1/2mv^2, and velocity varies depending on velocity of the observer, so does kinetic energy also vary depending on the velocity of the observer? for example, someone sitting in a bus who slides a 2 kg brick down the center isle of the bus at 5 m/s could say the has a kinetic...
