The joke might be on the dude with the gun since gunpowder needs oxygen no?

Going into space?

Belive it or not, also gambling.

Yes, in the manufacturing of the cartridge, but once it's made, it doesn't need an atmosphere containing oxygen to activate. The explosive charge behind the projectile is ready to go and just waiting for prime time.

Ah good info! Then there might still be the challenge of recoil?

[-] My_IFAKs___gone@lemmy.world 4 points 21 hours ago* (last edited 9 hours ago)

Newton's third law dictates there must be recoil. The momentum of the projectile and gasses exiting the end of the barrel must be exactly balanced by the force of holder's hand multiplied by the time it takes to arrest all motion of the recoiling firearm.

Momentum = definite integral of force as a function of time multiplied by the duration of time where momentum and force are both specific to an equivalent directional vector.

Could also use an energy analysis. The total kinetic energy of the projectile and exiting gasses will equal the handheld force multiplied by the distance the gun moves backward - more movement backward, less average force...in the limiting case of minimal movement backward, the force will be extremely high and short-lived.

Financial advice* and physics in the same thread? Now you're just showing off.

Yeah, much like if you take an m80 or many other fireworks and throw it in a lake it'll still explode, because the fuel the wick needs to stay lit is built in.
