1. The problem statement, all variables and given/known data 1) The time-dilation effect is sometimes expressed as "moving clocks run slowly" Actually, this effect has nothing to do with motion affecting the functioning of clocks. What then does it deal with? 2) Will two events that occur at the same place and same time for one observer be simultaneous to a second observer moving with respect to the first? 3)You are in a windowless car in an smooth train. Is there any physical experiment you can do in the train car to determine wether you are moving? 4)Does time dilation mean that time actually passes more slowly in moving refrence frames or that it only seems to pass more slowly? 3. The attempt at a solution 1)This is very hard cause it doesent really makse sense cause we just started learning about this. Well my answer would be that when moving faster light travels more therefore more time?? But regular clocks dont have cloks in them 2) yes if they happen in the SAME place wouldnt be simultanous to both? 3) there is nothing you can do cause all laws of motion are similar in two reference frames 4) Actually passes more slowly?
