Subject: Quick question on Gauss weapon recoil.
Just a quick question that someone better versed in physics than I can
answer. Why do guass rifles/pistols have a recoil value at all?
As I understand it, a rifle that uses gunpowder has recoil because of the
expanding gasses pushing back against the breach of the weapon (with the
equal but opposite force shoving the bullet down the barrel).
A guass rifle works by pulling the bullet down the barrel with an
electromagnetic field. Thus, no pressure agains the breech. I'm I missing
something really basic here?

Well Mark, what we have here is a simple case of Newton's second law.
The Electomagnetic force from the gun on the projectile can be see (and
is) as a force from the projectile on the gun. If you figure a 1 meter
barrel (which is actually longer than it probably is ) and the published
muzzle velocity of 1500 m/s. You can calculate the accelleration from
a=v^2/(2s) = 1.125E6 m/s^2. This is going to result in a recoil force of
F=ma where I assume the projectile is about 10 grams, making the recoil
force 1.125E4 Newtons which is the mass equivilent of 1.125 metric tons.
Quite a kick huh?
