hash marks or lines running parallel with the casing, caused by the inside of the barrel of the gun as the bullet travels out when fired
Yes, the bullet fired from a recoiling rifle typically has a greater velocity compared to the rifle itself.
science, Bullet markings and check them with the rifling of the firearm. Barrel twist and or markings can help ID the gun fired from. Nothing can tell you for sure, It can just tell you it was fired from a barrel like that of a type or make.
Yes, forensics experts can use a process called ballistics analysis to match a fired bullet to the gun that fired it. This involves examining unique markings left on the bullet by the barrel of the gun, such as striations or rifling marks. By comparing these markings with test-fired bullets from a suspected gun, investigators can determine if there is a match.
Yes, when a bullet is fired from a rifle, the bullet typically has greater momentum and kinetic energy compared to the rifle. This is due to the bullet's higher velocity and lower mass compared to the rifle.
A bullet fired from a gun has more momentum than a train at rest because momentum is the product of an object's mass and velocity. The bullet, despite being smaller in mass compared to the train, can have a significantly higher velocity, resulting in a greater momentum.
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.
The momentum of the bullet fired from a rifle is greater than the momentum of the rifle's recoil. This is because the bullet has a higher velocity and mass compared to the rifle, resulting in a greater momentum.
Assuming you refer to a fired bullet, you would examine the bullet- measure it's diameter, length, weigh it, and compare those to known specimens. You would also examine the bullet for striations- markings made by the rifling inside the barrel. The number and direction of twist of the striations may indicate a particular make of firearm.
Generally, when bullets are recovered at a crime scene, forensic experts analyze elements like gunshot residue and gun barrel markings to determine the sequence of fired bullets. Additionally, examining the bullet wounds on a victim's body can provide clues about the order in which the shots were fired. However, determining the exact sequence with absolute certainty can be challenging and may not always be possible.
The bullet fired from a gun has greater horizontal acceleration. For vertical acceleration, they are both the same.
I used gelatin or a large water tank.
When a bullet is fired into the sky, it will eventually stop becasue it has run out of energy and fall back to the ground.
