Well, you're free to define "negative mass" however you like, of
course--but this is not how physicists would use the term. When you plug
negative values of mass or energy into various physics equations it leads
to weird consequences that we don't see in everyday life, such as the fact
that negative-mass objects would be gravitationally repelled by
positive-mass objects, rather than attracted to them.
Jesse you are too quick. If you actually plug the right signs in Newton's
equations: F=ma and F=Gmm'/r2 you'll discover that positive mass attracts
everything including negative mass, and that negative mass repels
everything including negative mass.
You're right, I got it backwards, I was just going from memory there. The
negative-mass object will be attracted to the positive-mass one, while the
positive-mass object will be repelled by the negative-mass one. So if you
have two masses of equal and opposite magnitude, they'll accelerate
continuously in the direction of the positive-mass object, with the distance
between them never changing (at least according to Newtonian mechanics, it
might not work quite the same way in GR).
