Rifling a gun barrel causes the bullet to spin when it comes out. This makes the bullet fly more straight and greatly improves accuracy. Much like a spinning football spirals.
No. It will still fly straight.
.380 refers to the diameter of the bullet fired- and to the type of cartridge used by the gun.
Gun can refer to a long gun or a hand gun. A rifle is very particular. It has to have grooved barrel which spin the bullet when it is going down the barrel. This spin action on the bullet makes it more accurate.
It all depends on the gun and its specs like the guns velocity.
It makes the bullet spin when it is fired- much the same way a football spins in flight. The helps the bullet travel in a straight line, improving the accuracy of the gun.
When a bullet is fired from a rifled firearm, the rifling leaves marks on the bullet. Those marks are unique to that gun, and no other gun makes exactly the same marks. If a bullet (or fired cartridge casing) is recovered from a crime scene, and we suspect that YOUR gun was used to commit this crime, then a sample bullet is fired from your gun, and compared to the crime scene bullet. A comparison microscope is used to compare the bullets, or marks made on the fired cartridge case by the extractor and firing pin.
It causes the bullet to spin which makes it go straighter.
First ordinary bullets don't burn, it is the powder in the cartridge that burns.you could throw the bullet with your handyou could use a slingshot to propel the bulletyou could use high pressure compressed gas to force the bullet through the gun barrel (i.e. an air gun, a carbon dioxide gun)etc.
The gun weighs MUCH more than the bullet.
The total momentum of the bullet and the gun before firing is zero, as the gun and the bullet are at rest. Momentum is the product of mass and velocity, and since both the gun and the bullet are not moving, their momentum is zero.
It's the recoil from the force of the bullet being fired. The gun powder pushes the bullet forward and also equally pushes the gun back into your hand.
