IF the barrel is parallel to the ground, ALL bullets begin to drop as soon as they leave the barrel. To shoot at anything any distance away, the barrel is tiled up to some degree. Being pointed up, bullet WILL go up- and back down again. Try it with a stream of water from a garden hose, and you can see how it works. To spray water further away, you tilt the hose nozzle up- water goes up, and back down again. But point the nozzle straight out, water does not go up.

Why does a bullet seem to rise from a rifle?
the bullet rises because of the rifling in the grooves of the barrel
What is the bullet drop of a 22 cal long rifle?
There too many variables to give one answer- the drop is not even over distance, since the bullets begin to slow quite a bit at distances greater than 150 yards, It will vary depending on the speed of the bullet- and that varies by make, by bullet weight, and whether fired from a rifle, pistol, or revolver. When zeroed for 100 yards ,the trajectory of the standard high-velocity .22 LR with a 40-grain bullet has a 2.7-inch rise at 50 yards , and 10.8 inches drop at 150 yards .
Does a bullet rise or fall first after fired?
The sound may or may not "come first" when a bullet is fired. Particularly if we make the decision after collecting data from down range. The muzzle velocity of some firearms does notexceed the speed of sound. In those cases, the sound will reach a "target" down range before the bullet does. But the muzzle velocity of other firearms does exceed the speed of sound, and in those cases, the bullet will arrive down range before the sound does.
What will hit the ground first the bullet shot horizontally or the one dropped?
In theory, if a bullet dropped vertically at the same instant that a bullet is fired horizontally from a gun at the same height, they should both hit the ground at the same time.This example is used to emphasize that that horizontal motion and vertical motion may be analysed separately since they occur independently of each other.This is one of those things that works better in theory than in practice.There is a caveat that is important if you consider doing this in the real world. The process is not happening in a vacuum. The aerodynamics of the bullet fired at high speed is tremendously important. In early gun design, this was not understood and bullets fired from guns were very inaccurate and went up or down or right or left in unpredictable ways. Modern guns stabilize the trajectory by putting a spin on the bullet. The result makes the bullet act like a gyroscope and then to remain pointed forward when it encounters small anomalies in the air and wind. So, the moving bullet is subjected to vertical forces and can not be expected to drop at the same rate as a bullet with no horizontal motion.The principle of independent horizontal and vertical motion works better when illustrated by throwing and dropping heavy rocks. The principle is entirely correct, but there are more vertical forces involved than gravity with the bullets.
Does a 22 cal bullet rise at 75 yards?
no! all bullets fall. A bullet dropped from the edge of a table at the same time a bullet at the same table height leaves a barrel hits the ground at the same time.
Why does a bullet rise in flight?
It doesn't. As soon as a bullet leaves the muzzle gravity takes over and it starts to drop. ADDING: The bullet only appears to rise because it crosses paths with the line of the sights. A rifle's sights are usually located 1 to 2.5 inches above the center of the barrel. People normally adjust their gun sights so that the sights aim downward to cross the bore line at a point pretty close range (maybe 20 meters). But then while the imaginary straight line of the bore continues into the sky above the target forever, the real bullet, slowed down by air resistance and pulled down by gravity, will eventually drop across that line of sight again. This will be at a much longer range.
What is the only direction that net force is being applied to a projectile?
Projectiles in flight have two net forces acting on them. They've already been fired, so it is gravity (acting "down") and air resistance (acting "back") that are considered. There is a quirky factor called bullet rise or bullet drop that is a factor in long shots where a rotating projectile is used and a crosswind is present, but the two basic things acting on the projectile are gravity and atmospheric drag.
How fast does a bullet shot at a 90 degree angle hit the ground?
It is a common belief that a bullet fired at a 90 degree angle, perpendicular with the ground, will impact the surface simultaneously with a bullet dropped at the same altitude of the muzzle of the gun firing the projectile.However, this theory cannot be confirmed due to several exterior ballistic variables such as ambient air density (temperature and humidity), air resistance, wind, Coriolis effect, Eotvos effect, and the ballistic coefficient of the projectile.With all of these variables excluded, there is one thing that still disproves this common misconception.. That being the Magnus Effect.Magnus EffectThe phenomenon whereby a spinning object in the course of a forward vector is acted upon by a perpendicular force caused by the object moving through a liquid or gas.When a bullet is fired, the rifling in the barrel causes the projectile to spin in a clockwise motion (in most guns), this causes the bullet to veer from its forward vector due to water in the air (humidity).Without wind, this phenomenon causes the bullet to rise and move to the right. This effect is very important to marksman because wind can force the projectile to ^roll^ or drop- a bullet subject to a downward-left force due to wind hitting the right side of the bullet.This effect can be accurately predicted based on the rifle's turn rate, which can increase or decrease the effect because various rifles are made to fire with a turn rate of either 1:9 or 1:12, meaning the bullet will complete a revolution once every 9 inches, or 12.
Does rifling cause the bullet to rise?
It can. The rifling in the barrel causes the bullet to spin. This usually keeps the bullet moving relatively straight (because of gyroscopic stabilisation). However, as the bullet slows down at longer ranges, the spinning can cause it to wobble and drift. This is called spin drift. Spin drift can be upwards, so yes, rifling can cause a bullet to go up, but only at extreme ranges.
What technology allowed for the rise of European military dominance in the nineteenth and twentieth centuries?
The Automatic Rifle allowed for the rise of European military dominance in the nineteenth and twentieth centuries.
How far will a bullet travel when fired without a gun?
Not very far - several feet, perhaps, depending on a few things like caliber and what sets it off. The nature of Physics dictates that the lighter component will be launched. Generally the case (brass) is the part that is lighter. Smokeless powder burns, it does not explode. The burning of the powder in a restricted space (the chamber/barrel of a gun) enables pressures to rise and propel the bullet as significant velocity. Outside of these confines, the powder is not able to develop significant pressure. The inertia of the heavier component (often times the bullet) causes it to move very little. The lighter component will be launched but at a significantly reuced velocity from that which the gun barrel will propel the bullet. I have seen ammunition that "cooked off" in a fire. Generally the bullet is still in the case (brass) but the primer is the part that was propelled.
Who is more popular Rise Against or Bullet for My Valentine?
As of right now, Rise Against. Sometimes this thing is hard to gauge but RA has about 100,000 more listeners on last.fm, much more radio play, and their popularity momentum is still rising, whereas BFMV is at a relative stasis. This is a global-scale estimate. Bullet is probably more popular in their home country, the U.K.
