@bf2lover42 newtons third law applies everywhere, that's why it's a "law". A railgun accelerates the projectile by the Lorentz force, but the principle that the gun receives an equal push backwards as the projectile forwards always applies. Think of two magnets pushing each-other apart -- it's the same thing.

@bf2lover42 a railgun has far less recoil than a combustion-operated gun with the same projectile energy. However, accelerating the projectile forwards still accelerates the gun backwards. The big difference is that with conventional firearm, hot gasses continue to be propelled out the barrel long after the projectile, and those escaping gasses are the largest source of recoil.
they will always need massive amount of energy, there is just alot of energy needed to fire a projectile of multiple Kg at a speed 8 times that of sound
@zanta24 I allways wondered if using a liquid projectile might increase the lifespan of the rails. For example liquit mercury is both toxic and more dense than steel. Which I would think would make it an exceptionally good projectile for military applications. However, I wonder if it would scatter too much upon exiting the barrel to make it effective. Or if it would be too expensive a material to warrent it's use.
@MrAwsome514 That's kinda along the lines of a weapon in Mass Effect called a Magnetic-Hydrodynamic Weapon that shoots liquid iron-uranium-tungsten alloy that's shaped into an armor piercing shot. Now obviously alot of that while thoreticly possible not all that practical. what you may be able to do is if you could make a kind of magnetic rod that when diped in Mercrury would hold it like a magnet holds metel shavings, that may work and hold the projectile togher or at lease act as a buffer.
@MrAwsome514 And it also would only be useful if the military had chosen the scorched earth policy, because it is extremely toxic to wildlife and stuff.
@MrAwsome514 How would a liquid projectile work. A) it would BOIL and B) there is this thing called air resistance that would force so much force the mercury would ATOMIZE.
@MrAwsome514 xWOMBOCOMBOx is right, and no we don't need to shoot it to know. There are also two other problems: one, mercury isn't a ferromagnetic substance so how would you propose the rails would act upon the mercury? Asking nicely? If you put it in something that is ferromagnetic, you're right back where you started. Second, even a ferromagnetic liquid wouldn't work, because the liquid would be attracted to the magnetic rails and coat them. It needs to be a solid that keeps it's shape.
@Dallasdeckard You are not very familliar with how railguns function are you? Tell me how do the aluminum projectiles work then because they are not ferromagnetic either... The projectile is nothing more than a conductor. Is is the electromagnetic field around it that is acted on. Any suffeciently conductive material can be fired. Though you may be right that a ferromagnetic liquid might not work... I don't know how conductive ferrofluid is.
i would like to know what are you useing as ammo

@billzball .5" x .5" x 1" block of aluminum with a U cut out of the back. This is a pic of a projectile after a shot (didn't hit head-on)

How much voltage does this thing take? Also, how long does it take to charge, if any time at all?

Wat? Did I get the definition of railgun wrong, or am I missing something?
I thought a railgun was recoiless. I didn't know Newton's Third applied to this case.

@whoppix Yes, you are correct. It's like a person and the Earth. If the railgun's mass was large enough, it would be almost recoilless.

Can this be fired more than once, or did the projectile destroy the gun?
wii2050 1 year ago
@wii2050 Yes, it is reusable
zanta24 1 year ago
@wii2050 Yes, reusable. The projectile is not, and the rails need to be replaced every few shots.
