hi there, Thanks in advance for your answers.
my point is:
How can we calculate invariant mass?? What is the still(inercial) state??
This question comes from several books and web sites that I've search about it, and my problem was; ok: with velocity, a body makes is m turn to M by Y factor, but, what can we assume is the m? is the mass we calcule over volume and volumic mass? is the mass we height on Earth using "g" aceleration??
because, as the Earth itself is moving, then m is already being turned into M, and problaby, any other measurement is dependent of moving earth...
Another question about this is: considering E=Ymc^2 when v=/0, if a total aniquilation of a mass body hapens, what of this persons receive more E? A static person(considering referencial the mass body one), or a moving person?
My point of this question is: total energy depends on Y factor, so, if a mass body is still in relation to "A" and moving in relation to "B", "B" will receive more energy than "A" right? So in that case, the more faster we run from the explosion, the more energy we receive...:grumpy:
Once again, thanks...
