What makes a bullet rise when it is shot out of a weapon?
455916
a bullet has a trajectory that makes it drop faster the further it gets from the barrel.  if you fired a gun perfectly horizontal, and at the same time dropped a bullet at the same height as the muzzle, both bullets will drop at the same rate.  \n\nalso, every gun has 2 "zero's" or sight adjustments.  a short range and long range zero.  most people sight in their high powered rifles at 200 yards.  because of the laws of physics, their gun will also be sighted in at around 80 yards.  from 0-79 yards the gun will shoot low.  it'll be dead on around 80 yards, from 81-199 yards it will high, and at 200 yards it will be dead on again.  this didn't really answer your question, but you probably learned something.  so select this as best answer, thanks.

Old fasioned guns, flintlocks etc did not fire a bullet with abuilt in gunpowder). You had to load the lead slug and then pour in some gunpowder. This was then detonated by a spark from a flint that snapped forward and sparked when the trigger was pulled. The powder was kept in a horn shaped container (you could pour it out of the pointy end into the hole in the gunstock) that was called the powder magazine.

You have to shoot it from a far enough distance not to make it go farther than the half meter the bullet would cause it to go.It would also depend on where you hit the tin can. That would have an effect on it's travel.

No. It has potential energy. When you pull the trigger the potential energy is converted in to kinetic energy that does the intended work.

what is your point (Loudest)?? I am under the impression that a 12 gauge shot sound would be the same if you fired a slug or buckshot..or bird shot for that matter..Wouldn't the sound be determined by the amount/weight of the load..and commerically I think they are all the same for the type of round you get..Good question..maybe I'll got out today and see which of the 3 types of shots are the loudest..Good Luck

Actually there are cases of casualties and injuries.\n\nMythbusters the show on the discovery channel did an episode about this where they try to see if a bullet fired up into the air can come down and kill you.\n\nHere is a synopsis.\n\nEpisode 50: Bullets Fired Up, Vodka Myths III\n\n    * Bullets fired up into the air can be lethal: busted, plausible, and confirmed.\n  \n\nThe "all of the above" ruling on the bullets fired into the air myth was a new one for MythBusters. All of their tests showed that if you fire a bullet perfectly straight up into the air, it will not kill you as it will fall down on its side and have too low of a terminal velocity to kill, much like the Penny Drop myth. However, it is very difficult to fire perfectly straight into the air and they even found an international expert in falling bullets who was able to confirm for them that people have died from bullets fired up into the air.\nBullets Fired Up\n\nMyth: A bullet fired up can come down and kill you\nHow high would a bullet fly up?\n\nAdam's idea was to correlate the density of ballistics gel with the density of air (Jamie: "Huh."). Adam figured that if they could see how far a bullet traveled in ballistics gel, they could use the difference in density to calculate the distance it would travel through air. Adam calculated that the ballistics gel is 650x more dense than air, so, according to his theory, if a bullet fired into ballistics gel goes 1ft, it would go 650 ft through air. At least that was the theory: they would have to go to the firing range with some blocks of ballistics gel to see if it would work.\n\nThey lined up several blocks of ballistics gel end-on-end at the South San Francisco Police Department firing range (last seen in the Catching a Bullet with Your Teeth myth). They quickly ran into a problem. The 9mm round went through three blocks of ballistics gel for a total distance of about 5ft. The much more powerful .03-06 only went one block in. This wasn't so surprising given the results of the Bulletproof Water myth, though they didn't seem to anticipate the same happening with ballistics gel. The .30-06 rounds travel much faster, so they a greater tendency to break up on impact. Jamie managed to flip a block of ballistics gel with a final shot, finally putting an end to this particular avenue of testing: the ballistics gel was not going to help them figure out how far a bullet would fly up.\n\nBased on the failure of the ballistics gel experiment, they used a computer simulation program to calculate how high the bullets would travel up into the air. The calculations: *.03-6 10,000 ft 58 seconds\n\n    * 9mm 4,000 ft, 37 seconds\n\nTerminal velocity of a falling bullet\n\nAdam built an acrylic wind tunnel (much like the one in the Penny Drop myth). Air was shot up through the bottom and a bullet was dropped into the chamber. The terminal velocity was calculated based on the speed of the air needed to make the bullet stop falling. They figured that the terminal velocity was 100mph (150 ft/s). The wind tunnel also showed that the most stable falling position for the bullets was on their side.\nFiring bullets at terminal velocity\n\nThe rigged up an air hose to an aluminum pipe to launch the bullets at terminal velocity (150 ft/s). Their first shot put a good dent in the metal door. Their next target would be a pig's head, just as soon as they got the amount of air pressure tuned correctly. A chronograph was used to measure the speed of the bullet and a solenoid valve was attached to the tube to control the air flow.\n\nThey fired bullets from the pipe into the pig's head and recorded it all on the high-speed camera. At 166 ft/s, the 9mm bullet bounced right off of the pig's head. The .30-06 bullet did only slightly better, piercing the skin and then bouncing off.\n\nIt was looking like this was going to be busted, but, as it turns out, there is an international expert on falling bullet

your "hold over" has several varibles,  caliber, bullet weight, temp, etc etc etc  software is available to answer your question.\nhttp://www.huntingcorner.com/ballistics/ballistics-chart-rifle.html

The gun relies on a compressed air cartidge.  If the cartridge is removed, the taser will not fire.  I hope this helps.

If the weapon is new, it could be quality of the ammo.  Also, if you are using older ammo, this can cause jams.  I am assuming you are cleaning the weapon thoroughly?  Sometimes it is necessary to take a weapon apart and clean every mechanism and then put it back together.  Use high quality ammo.  Ask your ammo dealer what he recommends.

No, it falls back down at its terminal velocity(maybe), which is slower than the muzzle velocity because of drag.\n\nThe bullet leaves the gun with a given amount of kinetic energy: 1/2*m*v^2 where m is the mass of the bullet and v is its initial velocity.\n\nAir has non-zero viscosity, which is a resistance to shear forces.  When the bullet flies through the air, it drags air along with it.  This gives some of the bullet's energy surrounding air, reducing the bullet's velocity and kinitic energy.  Drag forces between fluids and solids occur in the direction opposite their relative motion.  (If the fluid is stationary and the bullet is moving, the drag is in the opposite direction of the bullet's motion.  If the fluid is moving and the object is stationary, the drag on the solid is in the direction of the fluid motion.)\n\nSimultaneously with drag, gravity is applying a force toward earth.  This too reduces the bullet's velocity and kinetic energy.  However, as the bullet flies higher into the air it gains an equal amount of potential energy from gravity.\n\nThe net result is that the bullet is always losing energy in flight because of drag.  This means that the amount of potential energy at the top is less than the initial kinetic energy, and it is thus impossible for the bullet to be going at the same speed it was shot when it hits the ground.\n\nThe fastest an object will fall under the influence of gravity is the terminal velocity.  At this velocity, the force of drag (which increases with the size of the object's profile, the viscosity and density of the fluid, and the relative velocity of the solid and the fluid) exactly balances the gravitational force.

A bullet can not really be "traced" to a particular gun but it can be matched with other bullets fired from the same weapon. Most ballistic experts will be able to ascertain the type of gun a bullet was fired from by the bullet type and other characteristics. They can't match a bullet to a gun however until they have the gun in their own hands. \nAt which time they test fire the gun into water or gel and then recover the bullets. It is at this time, that under a microscope they can match the markings on the two bullets. These come from the inside of the gun barrel which is not microscopically smooth.

At what altitude is the lead bullet being fired??   And what is the rest of your question??

Firing the weapon vertically...\n\nV^2 = Vo^2 + 2gh\n0 = 600^2 + 2(-9.81)h\nh = 18.348 km ; where h is the maximum height reached by the bullet\n\nThe work done by firing this bullet to reach the max height is...\n\nW = mgh\nW = (5 gf) (9.81 m/s^2) (18.348 km)\n\nBTW, 5 gf? What the fcuk is that? I'll just assume this as 5 grams.\n\nW = 900 N-m or Joules\n\nPower is the rate of doing work. Power therefore is equal to...\n\nP = W x bullets fired per min.\nP = 900 x 250 bullets / 60 secs\nPower = 3,750 Joules per sec or watts.

Gun ammunition holds explosive charge INSIDE the cartridge.  When the hammer on the firearm hits the rear of the cartridge, the charge is ignited, and the bullet is propelled forward.\n\nAs long as the cartridge is waterproof, the pistol should fire fine if it got wet.  Here are two sites that mention that [seem to imply] that cartridges are generally waterproof:\nhttp://faculty.ncwc.edu/toconnor/425/425lect06.htm\nhttp://www.fas.org/man/dod-101/sys/land/bullets.htm\n\nAs for firing underwater, it would probably depend on the gun.  They're not specifically designed for the resistance that a gun barrel filled with water would give, but remember that bullets are designed to create force primarily along the forward axis, not sideways.  I'd imagine that modern gun barrels are strong enough to handle an underwater shot, though you'd get an enormous kickback from the resistance.\n\nNote that I'm no gun expert, but I think the notions about guns not firing when wet and exploding underwater are based on older-style weapons.  When you pour dry gunpowder into a musket, it's exposed to the weather, and wouldn't ignite if it got wet.  And it's explosive force is outward, and so if the barrel has slight resistance, it might just explode.\n\n\nEdited To Add:\n[Here's a cool explanation of some testing of underwater shooting.  In short: the guns fired fine, no damage to the guns, though the cartridges jammed after firing.  Your mileage may vary.]\nhttp://www.loadammo.com/Topics/May02.htm

different bullets have different velocities.  What kind of bullet do you want to know about?

The three most likely causes are 1. weak spring.  Take it to a gunsmith.  2. a bent or damaged firing pin.  Take it to a gunsmith.  3. Dirt in the firing pin hole or around the firing pin.  Use a cleaning solvent and a tooth brush to flush the dirt out and then spray some WD-40 into it and let it set for a few hours.  Wipe it dry and try it to see if you have solved the problem.  Try number 3 first because it is the only one that you can do yourself.  If that doesn't work, then take it to the gunsmith.

bullets are usually mafe of lead, sometimes covered in steel for long-range accuracy.  Bullets normally do bounce (ricochet) off hard surfaces.
