When a rifle with a longer barrel is fired the force of expanding gases acts on the bullet for a longer distance what effect does this have on the velocity?
To a point, the velocity of the bullet will increase. However, at some point, the gasses driving the bullet have maxed out, and beyond that point, the bullet will begin to slow from friction with the barrel. For a .22 LR cartridge, that length is about 12 inches. Larger cartridges have a greater "Max velocity" length, but there is a point of no more gain, and the start of loss of velocity.
What else can I help you with?
Does a bullet shot from a gun undergo any acceleration after it leaves the barrel?
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
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.
Why does a bullet have less momentum fired from a short barrel vs long barrel?
At the instant the gun fires, the bullet is at rest- speed zero. As the expanding gasses from the burning gunpowder reach the bullet, they begin pushing the bullet up the barrel. It's speed is increasing- and the longer the push, the higher the speed. There IS a point of diminishing returns- where a barrel LONGER than the perfect length begins to slow the bullet- you have used all the expanding gasses, and now friction is slowing the bullet. If you had a barrel 20 ft long, the bullet would not make it all the way up the barrel, it would stop.For barrels on any realistically-usable weapon, a longer barrel will provide more momentum to the bullet than a shorter one. In addition, longer rifled barrels will also impart more spin, which will increase accuracy.
Define trAjectory of the bullet velocity of the bullet velocity?
Bullet trajectory is the path the bullet travels once it leaves the barrel. Bullets travel on a long arch and cross the line of sight twice. Once shortly after leaving the barrel and once again on target assuming the sights are properly zeroed. This is the trajectory of the bullet. Bullet velocity is the speed at which the bullet is traveling along it's trajectory.
What is the Difference between muzzle velocity and recoil velocity?
Muzzle velocity is the velocity of a bullet as it leaves the firearm's barrel, while recoil velocity is the backward momentum that the firearm experiences when the bullet is fired. Muzzle velocity determines the bullet's speed and trajectory, while recoil velocity affects the shooter's ability to control the firearm during and after firing.

What happens in a gun barrel?
Barrel contains the force of expanding gasses, as it pushes bullet out of the barrel.

How fast is a pistol bullet?
Too broad a question. Muzzle velocity is determined by the specific cartridge, barrel length, barrel tolerances, etc.
How bullets work?
A bullet is the part of a cartridge that is fired from the gun. A cartridge consists of a cartridge case, primer, powder, and the bullet. The primer is struck by the firing pin, and explodes. In doing so, it ignites the gunpowder. Rapidly burning powder produces a rapidly expanding gas. This pushes the bullet out of the barrel.
What is the bullet drop for a 180 grain bullet shot from a super red hawk with a 9.5 inch barrel and a suggested O in range for a scoped?
The bullet drop will vary based on factors such as caliber, muzzle velocity, and distance to the target. For a 180 grain bullet shot from a Super Red Hawk with a 9.5 inch barrel, using a scope for sighting can help improve accuracy and account for bullet drop at longer ranges. It is recommended to zero the scope at a specific distance (e.g., 100 yards) to minimize bullet drop over different distances.
Why does a gun pop?
The bullet is quickly pushed out of the barrel by rapidly expanding gasses from the burning gunpowder. Those expanding gasses push the air when the bullet leaves the gun, making a POP or POW or BANG.
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.
What happens to a bullet as it moves down the barrel of a firearm?
As a bullet moves down the barrel of a firearm, it gets propelled by expanding gases from the ignited gunpowder. The rifling inside the barrel causes the bullet to spin, improving its accuracy by stabilizing its flight. The bullet gains speed and energy as it accelerates down the barrel before exiting the muzzle.
