A bullet is propelled by the controlled explosion of gunpowder in the cartridge. When the gun's firing pin strikes the primer, it ignites the gunpowder, which rapidly expands to create gas pressure that propels the bullet down the barrel and out of the gun.
If you drop a bullet and it hits the ground will it explode?
No, a dropped bullet will not explode upon hitting the ground. The impact may cause the bullet to deform or potentially discharge if it is struck in a specific way, but it will not explode like a firework.
How far will a 9 mm bullet travel when fired?
The distance a 9mm bullet can travel when fired depends on various factors such as the muzzle velocity of the firearm, the angle at which it is fired, and environmental conditions. On average, a 9mm bullet can travel up to 1.5 miles when fired from a handgun and up to 2.5 miles when fired from a rifle.
Bullet ballistics refers to the behavior of a bullet in flight, including factors such as velocity, trajectory, and accuracy. It involves studying the impact of various variables like distance, wind speed, and bullet design on the bullet's performance upon firing. Understanding bullet ballistics is essential for precision shooting and hunting.
How does the grain of the bullet affect the accuracy of the shot?
The grain of a bullet refers to its weight. Heavier bullets typically have better stability and accuracy compared to lighter ones, as they are less affected by wind and other external factors. However, the specific gun, barrel length, and shooting conditions also play a significant role in determining accuracy.
Shoot a 30 30 bullet straight up how far does it go?
When a .30-30 bullet is shot straight up in the air, it can reach an altitude of around 1 to 2 miles before losing momentum and falling back to the ground. The actual height depends on factors such as the angle of the shot, the bullet weight, and environmental conditions.
The mass of a bullet is nowhere near the mass of a gun. A bullet weighs at most a few hundred grains. Most guns weigh at least a couple of pounds, some weigh several pounds (talking about handguns and rifles).
The barrel of the gun has lands and grooves (grooves and ridges) cut in a spiral. The bullet molds to these and starts to spin as it moves down the barrel. The bullet just continues to spin after it leaves the barrel.
<><><>
Correct. The ridges are known as 'lands'. It is possible to calculate how fast a bullet will spin if you know the twist rate of the barrel and the velocity of the bullet. My AR15 has a twist rate of 1-in-8 ie for every eight inches the bullet travels down the barrel, the bullet is rotated once. It fires a .223 round at approx 2,800 feet per second so... The formula is (bullet velocity x 720)/twist rate so... (2,800x720)/8 is an incredible 252,000RPM!
Does a bullet train travel faster than a bullet?
bullet trains travel at 96.5 percent the speeed of a bullet
No it doesn't. A bullet train does around 190mph normally and can reach 275mph. Depending on calibre, a rifle bullet travels at 1,500-2,000mph. So on average, a bullet train travelling at normal speed travels at between 9.5 and 12.6% of the speed of a rifle bullet.
How do you measure bullet size?
Bullet size is typically measured by its diameter in inches or millimeters. This measurement is taken at the widest point of the bullet, known as the caliber. It is important to accurately measure bullet size to ensure proper fit and function in firearms.
How does a hollow point bullet work?
When a hollow-point hunting bullet strikes a soft target, the pressure created in the pit forces the material (usually lead) around the inside edge to expand outwards, increasing the axial diameter of the projectile as it passes through. This process is commonly referred to as mushrooming, because the resulting shape, a widened, rounded nose on top of a cylindrical base, typically resembles a mushroom.
The greater frontal surface area of the expanded bullet limits its depth of penetration into the target, and causes more extensive tissue damage along the wound path. Many hollow-point bullets, especially those intended for use at high velocity in centerfire rifles, are jacketed, i.e. a portion of the lead-cored bullet is wrapped in a thin layer of harder metal, such as copper or mild steel. This jacket provides additional strength to the bullet, and can help prevent it from leaving deposits of lead inside the bore. Incontrolled expansion bullets, the jacket and other internal design characteristics help to prevent the bullet from breaking apart; a fragmented bullet will not penetrate as far.
What is the average speed of a bullet?
== ==
It varies alot. The older, larger rifle calibres are generally around 2,100 to 2,500 feet per second. Standard modern rounds like .308, 6.5x55, .30-06 etc are generally around 2,500 to 2,900 feet per second. Modern varmint calibres like the .22-250 and .204 Ruger for example can exceed 4,000 feet per second.
Heat created by burning powder expands in its environment faster than the speed of sound. The heat from Lightning ,static electricity, causes expansion greater than the speed of sound. The speed of the expansion, and what the resulting sound bounces off of, determines what we hear.
AnswerA bullet travelling down a barrel doesn't create a vacuum. The force of the gas when the bullet is fired is around 50,000+ PSI. As the bullet leaves the barrel, the gas pushing it is still over 10,000 PSI. This causes the roughly 170dB bang a rifle makes when it is fired.
Most bullets have a pointed or rounded "nose" and flat end. Ball ammunition are round balls. Although these may still be fired through rifled barrels, ball ammunition is typically fired from a musket rather than being loaded into a modern cartridge.
How does a tracer round of ammunition work?
A tracer bullet is made by filling a hollowed out area in its base with phosphorus or magnesium. When fired, the gunpowder explosion ignites the material; as the bullet travels, it leaves behind a bright glow, smoke, or both. Barium salts are used in some ammunition as well, and these glow green.
Some specially-designed bullets only begin to glow (or glow at full strength) after they have traveled some distance. This allows the shooter to see how close he is to the target, without the enemy using the tracer to pinpoint him as the source.
Often, in addition to being used for accuracy, tracers are placed at the bottom of a clip so that you know when you're almost empty.

1 A force of 2.1N is exerted on a 7.0-g rifle bullet What is the bullet's acceleration?
Using Newton's second law (F=ma), the acceleration of the bullet can be calculated by dividing the force by the mass of the bullet. First, convert the mass of the bullet to kg (7.0g = 0.007kg), then divide the force (2.1N) by the mass (0.007kg) to find the acceleration. The acceleration of the bullet would be 300 m/s^2.
What happens to a bullet when the shot is to the air?
Very basically, every bullet fired up or at an angle comes down SOMEWHERE. It may come down and hit the ground, a house, some other structure, a person, etc. Don't know if you meant anything beyond that.
What is the velocity of a bullet?
It depends on a number of factors including propellant charge, bullet weight and barrel length.
Handgun muzzle velocities range from about 750 feet per second and 1350 fps. Ordinary rifles go up to about 3,000 fps. Some specialty rounds go above that.
For an idea of the variation: using the same 357 Magnum round, a snub-nosed revolver will eject the bullet at 1,100 fps, a match revolver at 1350 fps and a 16" barrel rifle at 1,850 fps. Your standard-issue .45 cal pistol ammo has a muzzle velocity around 850 fps.
If you throw a bullet into a fire and it goes off will it travel far?
No. It depends upon the bullet of course, but a handgun bullet usually won't hurt you if it hits you under those conditions. Another answer: Depends on the cartridge: Remember that this is deadly because the bullet and cartridge will go in opposite directions at great speeds. The larger the bullet and powder will determine the velocity and distance.
How do hollow-point bullets work?
The hollow in the tip of the bullet allows soft tissue to enter into the bullet causing rapid expantion.
The hole in the center of the bullet allows for the bullet to expand to a wider diameter upon impact. Thusfore causing greater damage to the target
A hollow point has a pit or hollowed out shape in its tip, generally intended to cause the bullet to expand upon entering a target in order to decrease penetration and disrupt more tissue as it travels through the target. They are also used to control penetration, such as in situations where over penetration could cause collateral damage (such as on an airplane). Jacketed hollow points (JHPs) or plated hollow points are covered in a coating of harder metal to increase bullet strength and to prevent fouling the barrel with lead stripped from the bullet. The term hollow-cavity bullet is used to describe a hollow point where the hollow is unusually large, sometimes dominating the volume of the bullet, and causes extreme expansion or fragmentation on impact.
How close is a bullet when you hear the whizzing sound of it passing by?
The whizzing is the sound of the bullet cutting through the air very quickly, it also denotes rotation in the projectile. The sound is audible to the human ear within a distance of 2 Meters or 6 feet. The heavier the whizzing the closer the bullet.
First the answer
If you fire the gun on Earth then no, the bullet comes back down slower than it left.
Now for the physics which explains the answer.
The simplest way to look at this question is probably to use conservation of Energy. You could arrive at the same answer using Newton's laws but it becomes involved. First less us consider firing the gun in a vacuum. The kinetic energy (movement energy) of the bullet when it leaves the gun is gradually converted into gravitational potential energy as it moves up and slows down. Eventually it reaches its highest point and stops. It has zero kinetic energy, all the energy has been converted into gravitational potential. The bullet then starts to fall under gravity. The gravitational potential energy is converted back into kinetic energy. No energy is lost so the bullet arrives back where it started with the same kinetic energy it left with or to put it another way at the same speed it left. If you tried this on Earth it would not happen. The bullet would be subject to air resistance (friction from the air) on the way up. Some of the kinetic energy would be converted into gravitational potential, some would be lost heating the surrounding air. The same would happen on the way down, some energy would be lost. The bullet would arrive back moving more slowly than it left.
An alternate way of looking at it is to use the concept of terminal velocity. It is not as compete from a physics point of view but it may be easier to understand. The bullet, once at the top of the trajectory has no energy left from the gun, all of the energy from that point forward comes from gravity. Any object falling in a gas (like the atmosphere of Earth) can only reach a certain speed, its terminal velocity before the friction from the surrounding gas is equal to the force from gravity. This speed is called terminal velocity. It is determined by the size, shape and mass of an object. The terminal velocity for a bullet is likely significantly less than the muzzle velocity.
What happens to k.e. of a bullet when ita penetrates into a target?
When the bullet penetrates into an object its velocity decreases very much or becomes 0 suddenly. This causes a change a momentum of bullet and impulse is applied. Technically the kinetic energy is converted to potential as a deformation occurs inside that object, transferring some of the kinetic energy into the object.
