Bullet Speed but in space

[HakutoRei000]

Suppose a bullet is fired in space (or on Mars, or in a high-gravity environment), and the bullet is manufactured so that its speed and acceleration are not affected by gravity.
Would the calculations be different, or should we still use the standard calculation methods?

Initial velocity would still be the same. It would take longer to descend in lighter gravity and thus average velocity and by extension range would be higher. In higher gravity environments, same process in the opposite direction, same initial velocity but higher gravity would make average velocity and firing range much lower. If fired in outer space, it would just be a static initial velocity until it hits something or gets close to another gravitational field effecting it.

There are all talking about standard bullets, if you're talking about firearms specifically designed to function in high gravity environments, they might be much stronger/faster and use materials stronger than gunpowder. But it may be difficult to find specific details.

What about acceleration? Does it change? Say if the gun/bullet specifically changed in its acceleration rate so that it can move as fast as on earth even with gravity and other factors.

Do you mean the acceleration causing the initial velocity so that the average velocity would be roughly the same as on Earth?

Both, the initial and after the first shot.

I'm not sure how you mean, the way you're asking it is quite confusing. But there are many many factors to take into account when it comes to calculating bullets speed. Initial muzzle velocity is just the surface, but the weight of the bullet combined with the cross sectional area can determine gravity resistance which in turn affects average velocity and overall firing range. In order to maintain same average velocity and firing range in a higher gravity environment, putting more gunpowder to raise KE and thus initial velocity is one method. But there's also firing bullets with a higher cross sectional and/or lighter mass.

Alr thanks, sorry for my bad english.
