well then let us assume electron and neutron moving in direction of electric field.then, with respect to nuetron, is electron gaining energy when it is actually becoming slower relative to earth?
watching from Earth frame, i see an electron lose a photon and get slower. but if i consider a frame still moving with initial velocity of electron, what do i see? the electron looses a photon,but moves faster. hence its relativistic mass is also greater than rest mass.total energy has increased...
well thanks to all for helping me with the topic. specially thank tiny tim and my wan(i found that a funny name). thanks a lot to kev,bose and others too. i have understood much about relavity, (though i have a separate theory about it) and i have got the answer to the question i posted...
"No … you're ignoring the fact that he can detect gravitational potential difference by comparing his own clock to another clock at another corner of the spaceship.
So long as you allow him to put his detecting machine a few feet away from him, he can detect acceleration.
The gravitational...
dear tiny tim.
you had said about the case where two bodies collide and return, that the acceleration is huge.i don't have much knowledge about change in time due to acceleration. but even then i have a doubt. may be sometime long ago before Earth was formed, it had some good acceleration with...
"Acceleration as I said is not relative. You are confusing acceleration and relative motion. Here's why: When you are in a box that you can't see out of you always know when you are accelerated because you will feel a g force pushing you. When you and your friend are moving away from each other...
"No … you can always detect acceleration … you can carry out very simple experiments to show it … for example, just letting go of something and seeing if it moves away from you!"
that is in case only the ship is accelerating. when accelerations like gravity act, they will act on the object...
"Yes, but only during steady speed … the acceleration cancels out all the time lost during steady speed!"
first, i didnt understand that...
second, let's remove acceration this way first...
bodies move away from each other with constant relative velocity, suffer a near elastic...
"You didn't say they did. We're not going to read things in unless they're obvious, and that certainly wasn't!"
sorry if i didnt... i am prone to blunders...
