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?
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.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.i was wondering if anyone knew how to derive the magnus effect equation?
