The velocity rate of change of an object's position with respect to some frame of reference. Velocity is a function of time.

THE CHARGE AND THE PARTICLE ITSELF WOULD BE DIFFERENT. An atomic particle is at rest with respect to itself. Thus an Electron's rest mass is the mass itself would measure. Again, if you want to know the particle's energy (including the energy equivalence of its rest mass) relative to some other frame, then you need to account for the other forms of energy. But these energies won't be the same in all frame, and thus different frames would have different values for the total energy for the particle. This is what makes rest mass such a useful concept. It is a value that all frames can agree on. It is frame invariant rather than frame dependent.
hypervalent_iodine Posted October 15, 2019 Posted October 15, 2019 ! Moderator Note Since this is mostly just confused ranting, I am closing this. Ville502, if you have something you wish to discuss please do so in a more appropriate manner that shows you have actually put some thought into your ideas. IOW, produce scientific arguments to back yourself and quit with the all-caps. 1
