Would a bullet have longer trajectory,because the air helps it ''glide''?Does this mean that if you fire the same gun and bullet in vacuum and in the air the one fired in the vacuum will fall to the ground a lot more quickly?
K^2 said:Actually, the fired bullet does stay in the air slightly longer. Even though it does not glide,

I can confirm this with a quick simulation, under the assumption of a spherical bullet without rotation - but I do not think those things change the result.K^2 said:Actually, the fired bullet does stay in the air slightly longer. Even though it does not glide, the vertical drag is effectively increased. But it's not nearly enough to offset the loss of speed due to friction, so the range is still significantly reduced.
Sort of. At least, in a somewhat idealized setup, which should give you a qualitative answer, at least.ben682 said:i was wondering if anyone knew how to derive the magnus effect equation?
Yes, air friction can affect the range of a gunshot bullet.
Air friction, also known as drag, creates resistance against the bullet as it travels through the air. This resistance slows down the bullet and reduces its range.
No, air friction cannot increase the range of a gunshot bullet. It can only decrease the range.
The amount of air friction on a gunshot bullet can be affected by several factors, including the bullet's shape and size, the speed at which it is traveling, and the density of the air it is traveling through.
To minimize the effects of air friction on a gunshot bullet's range, the bullet's shape can be designed to be more aerodynamic, and it can be given a higher initial velocity to reduce the amount of time it spends in the air.
