Yes, momentum. If you take something that is standing still and throw it
forward you will go backwards regardless of *how* you throw it. But don't
worry, the New York Times made the same error once in an editorial about
Goddard:)
The recoil of a gauss weapon of a specific damage will however often be
*less* than for a conventional weapon of the same damage, because first of all
you don't throw bullet+gasses but just the bullet. This should reduce it by
25 percent or so.
Secondly, speaking 3G3, gauss weapons have more slender projectiles that
penetrate better for a given energy, so to get a specific penetration and
a specific damage, you can make do with a lighter projectile, also reducing
recoil.
I suspect that adding both effects will aproximately halve recoil compared
to a conventional weapon of equal damage.
