I'm not sure exactly what you mean by stuff having a lower mass in a potential. The potential should lower the object's energy but not its mass. Most physicists define mass to be invariant (m^2*c^4=E^2-(pc)^2 is a frame independent constant) so your momentum is gamma*m*v instead of m*v with a varying m. If you are going with a definition of mass where m=gamma*m0 though the only thing that affects the mass is the object's velocity. --- Congrats to BKSheikah for winning the BYIG Guru Challenge! ...
