Reply to comment by Aquaticulture in Maybe you all can settle this debate. What happens when you fire (Wait for it) a gun with a recoil suppression system, such as the KRISS Vector, in vacuum? by TyphusIsDaddy

Micro gravity is probably what I meant, Im definitely not a scientist. Whats the difference?

Also I thought mass would still be relevant, just couldnt work around how. Is it because the energies from the bullet are being transfered into the recoil dampners/springs, but theres nothing counteracting the weight of the bullet?

Not a physicist but the way I understand it you’re always subjected to some amount of gravity in space, but as you’re orbiting the planet/sun/galaxy/center of mass you’re constantly in freefall.

Micro gravity and a vacuum are two different environments. We can create a vacuum on the surface of earth (full of gravity) or have the space station have micro gravity with no vacuum inside the station itself. The depths of space have both micro gravity and a vacuum.

Mass is certainly relevant in micro gravity. Kinetic energy (like a moving bullet) is bound to mass. More mass, more kinetic energy. So if you were to shoot a heavier bullet at the same speed as your vector, the bullet would have a higher energy. Then equal and opposite forces blah blah blah...
