Does the velocity of a 22 caliber bullet change with the length of the barrel?

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.

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 far do a bullet go in the air?
There is no limit depending on the gun and the bullet. A gun could be made to shoot a bullet out of the solar system. A gun could never fire a bullet fast enough to escape Earth's gravitational field because doing so would inevitably lead to the bullet's vaporization due to its friction with the atmosphere, much as incoming meteors burn up when they enter the atmosphere. However, a rocket can escape Earth because it maintains a relatively low velocity to avoid burning up. Once in the near-vacuum of space, velocity can be increased without fear of vaporization.
Under what circumstances can an object move in a circular path without being accelerated?
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't.

What causes a spaceshuttle to change in velocity by change in direction?
A change in velocity constitutes a change in direction because velocity includes direction.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.

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.
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.
Is shooting off fireworks a chemical change?
Not exactly. When the trigger is pulled, a hammer strikes the back of the bullet with a lot of force. This force ignites the gunpowder within the shell of the bullet, propelling the bullet forward. From there, the bullet hits a target, and they die.

Rate of change of the velocity of an object?
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".

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.

"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
