Yes. The velocity of all common cartridges changes with the length of the barrel. In the case of a .22 LR, they develop the maximum velocity between 12 and 16 inches of barrel. Shorter than that, the gasses from the gunpowder have not accelerated the bullet as much as they can. Longer than that, gasses reached their max acceleration, and the bullet is now slowing from friction in the barrel.

What the work energy theorem of a rifle with a longer barrel that fire bullets with a larger velocity than a rifle with a shorter barrel?

The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. In the case of rifles, the longer barrel allows for a longer acceleration distance for the bullet, resulting in a higher muzzle velocity. This means that the rifle with the longer barrel does more work on the bullet, giving it more kinetic energy and a higher velocity compared to the rifle with the shorter barrel.


How fast does a bullet accelerate when it leaves a gun barrel?

A bullet does not accelerate after it leaves the barrel of a gun. It will decelerate. You could say it accelerates, but the acceleration would be negative. The bullet is accelerated by expanding gas as it moves down the barrel, and after it leaves the muzzle, there is no more acceleration imparted from expanding gas. We also find that air friction (drag) is acting to slow it down. Think this one through and it becomes obvious.


How does a hot barrel affect the accuracy of a firearm?

A hot barrel can affect the accuracy of a firearm by causing the metal to expand, which can change the dimensions of the barrel and affect the trajectory of the bullet. This can lead to decreased accuracy and consistency in shot placement.


When a 60g bullet fired from 5kg gun leaves with a speed of 500ms. Find the velocity with which the gun recoils?

By conservation of momentum, the momentum of the gun and bullet system before firing must equal the total momentum after firing. Therefore, the velocity at which the gun recoils can be calculated by using the equation: (mass of bullet * velocity of bullet)/mass of gun = velocity of gun. Substituting the values given: (0.06 kg * 500 m/s) / 5 kg = 6 m/s.


How do you calculate the change in velocity of an object?

To calculate the change in velocity of an object, you subtract the initial velocity from the final velocity. The formula is: Change in velocity Final velocity - Initial velocity.

Do you need to change 357 barrel to shoot 38bullets?

Change the 357 and 38 to decimals. .357 .380 Since a 38 caliber is larger than a 357 caliber, it would be wise to change barrels and consult a gunsmith. If you have to ask this question, you need to talk to an expert before proceeding. No, yoou need not change the barrel. Both have the samebullet diameter. You can shoot a .38 in a 357 but not vice versa. Why? because the length of the bullet is different. both are 38 caliper.


What does 30.06 mean in a bullet?

Let's use the correct term- CARTRIDGE. Bullet is the PART of a cartridge that comes out of the end of the barrel. The 30-06 (usually pronounced as thirty ought six) is a .30 caliber rifle cartridge- meaning that the bullet is 30/100ths of an inch in diameter. It was developed in 1906. It was called that to help distinguish it from an earlier .30 caliber cartridge- the 30-40 Krag (which had a .30 caliber bullet, driven by 40 grains of black powder, and was created by the Krag/ Jorgensen Company) Naming practices tend to change over time, and are not always uniform. Good question, tho.


How many feet per second for a 22?

The speed of a .22 caliber bullet can vary depending on the specific ammunition used, but it typically travels at around 1,000 to 1,200 feet per second. For example, standard .22 Long Rifle ammunition usually has a velocity of about 1,080 feet per second. This speed can change based on factors like barrel length and environmental conditions.


Can you change the barrel of a pistol to another caliber?

If the barrel is thick enough and it's a small caliber change to a larger size, it can be done. But it requires specialized barrel milling machinery, and the quality will never be as good as the original caliber it was designed for. Also; you would need to install a different chamber that would handle the larger round, as well as a new magazine. All in all, you're better off just to buy a new gun in the caliber you want.

What effect does temperature change have on bullet drop?

Temperature can have two primary effects. First, keep in mind that the rate a bullet drops always remains the same. What changes is the amount of range we can get out of a bullet before it drops a certain amount. The first effect is that generally, higher temperatures means more initial velocity when the bullet leaves the barrel. This usually means more range. The second effect is that the air is less dense, and therefore creates less drag on the bullet. Again, this means more range.


An average force of 4000 newtons acts for 0.01 seconds on a bullet of mass 50g calcualte the speed of the bullet?

50 g = 0.05 kgF = m AA = F/m = 4000/0.05 = 80,000 meters per second2If the bullet starts from rest and no other forces act on it, thenSpeed = (acceleration) x (time) = (80,000) x (0.01) = 800 meters per second

Can you switch the caliber of your Desert Eagle by changing out the barrel and bolt?

Yes you can. You can change from a .50 to a .44 by just changing the barrel. The bolt stays the same. You can also change to a .357 but that requires a different bolt as well. The magnum research company sells all these conversion kits on their website.
