I was reading the Wikipedia page on "Mass in Special Relativity" (http://en.wikipedia.org/wiki/Mass_in_special_relativity) and I came across two equations:
M = m/sqrt(1-v2/c2)
and
p = mv/sqrt(1-v2/c2)
along with the following quote:
Einstein's comment seems to suggest that the perceived increase in mass is due to the increase in momentum. If mass itself were increasing, you would expect to see an increase in the gravitational field around particles moving at relativistic speeds. But that increase might be undetectable. Can anyone here tell me how scientists might be able to discern between the two possibilities, or better yet, if it's already been done?

and
p = mv/sqrt(1-v2/c2)
along with the following quote:
Albert Einstein said:It is better to introduce no other mass concept than the ’rest mass’ m. Instead of introducing M it is better to mention the expression for the momentum and energy of a body in motion.
