hi every one :)
i need a small help please ...
we have tow frames and tow observers , let suppose there is a force on an object in one of the frames , so from Newton law:
f=ma
"a" depend on "x" distance which is not constant in the other frame , so why they assumed that it is constant as the mass ?!
of course i am talking about the period before modern physics of Einstein and the electromagnetic theory.
thanks a lot ...
