(4,184 posts)Simple questions....
In my scenario... you fire a railgun. The propulsion moves the ship opposite direction of the projectile. Since there are two railguns the propulsion is doubled. I don't think any one has any issues with this event.... simple and straightforward.
Next event....
The projectile is tethered and enters an arc... conserving the linear momentum and now subject to the laws of conservation of angular momentum... or is that not true? Does this scenario negate the effect of those laws and how?
The arc redirects the momentum of the projectile 180 degrees so that the projectile is released travelling in the same direction as the ship...
The projectile is caught and stopped dead by a magnet and the ship then reabsorbs the force.
So ship is moving in direction A...
Projectile in direction B
Projectile enters an arc conserving linear motion... subject to the laws governing the conservation of angular momentum now...
The force is redirected... assuming we are allowed to redirect force in space... is it different than on Earth?
Projectile is now traveling in direction A : The projectile is now traveling in the same direction as the ship before it is rejoined.. and the forces aligned in the same direction...
Questions? How does the fact that the linear motion is conserved when the projectile enters the arc allow for the linear motion to be removed from the system since is supposed to be conserved...
Question... how does the projectile that is traveling in the same direction as the ship subtract force when forces moving in the same direction are supposed to add together and not subtract.
You can feel free to quote me all the laws you like and call me as stupid as you want... I just would like an answer to those questions.
