between the magnets exerting force imparting momentum inward and the projectile exerting force outward in response. Thus the momentum sum continues to zero itself.
If the forces exerted are symmetrical then the projectile goes nowhere. If the forces are asymmetrical the launcher accepts the inverse of the projectiles acceleration, summing the system to zero. Unless you are using a definition of recoil different than any I have ever seen, the rearward movement of the launching mechanism in response to the acceleration of the projectile is the recoil.
Nice to meet you too. Can you think of another way to respond to my posts other than an insult? I wish you well and better in your future endevours.
