The Physics of Firearms - 1626 Words

Firearms are often featured on the news due to poor use as well as featured in popular culture’s television crime dramas, but have you stopped to ponder about where these devices came from, the different types, the trajectory patterns that are created their bullets and how they work? The following paragraphs are designed to address all of the following questions. A firearm is a complex arrangement of various metals that can eject a small lead piece at high speeds, causing maximum destruction on the target with minimum energy delivery on the shooter themselves. (Definition of a Gun, n.d.) The mechanics of shooting any type of firearm; weather it be a rifle, shotgun, or pistol, includes a wide variety of physics topics working together to make the bullet hit its target including friction, force, conservation of momentum, transfer of energy, heat engines, and projectile motion. (The Physics of Shooting a Gun, n.d.) History Of Firearms The history of firearms begins in China in the ninth century where, huo yao, the world’s first gun powder was discovered; it was created by mixing charcoal, potassium nitrate and sulphur into a fine powder. Historians are prone to recognizing tenth century Chinese fire lances, a spear-like weapon combining a bamboo tube containing huo yao and projectiles tied to a Chinese spear as the first firearm. In the year 1320, Gun powder was developed into a specific formula, 15% charcoal, 75% potassium nitrate and 10% sulphur. It was developed for theShow MoreRelated Physics of Firearms Essay620 Words   |  3 Pagesactivity and it is enjoyed by many people, so much so that it is also done at a competitive level. Although many people may have shot a firearm of some sort, few of those people actually realize how much physics is involved with the shot. So what exactly is Ballistics? Ballistics is the science or study of the motion of projectiles and in the case of most firearms, these projectiles are the bullets. There are two things that affect the flight of a bullet once it has been shot out of the gun. TheseRead More Physics of Firearms Essay1363 Words   |  6 PagesA firearm, in the most basic form, consists of a barrel, an action, a firing mechanism, a stock and a sighting device. No matter the form of the firearm, the same basic principles of physics and chemistry apply. The study of these principles is called ballistics. There are three types of ballistics, internal, external, and terminal. Internal ballistics is the study of the flight of a projectile inside a firearm. External ballistics is the study of the flight of a bullet after leaving the muzzle andRead MoreThe Field Of The Military Field1313 Words   |  6 Pagesgreat deal of discipline in order to be successful. One has to endure arguably the hardest schooling out of any major, which includes juggling years of higher level of mathematics and its applications with several rigorous scientific classes such as physics, thermodynamics, and chemistry. One has to discipline oneself especially with time management and sharpness to be able to meet the demand placed on them to graduate. Simply said, one cannot slack even slightly in the engineering field otherwise heRead MoreCryogenics Essay835 Words   |  4 PagesIn Physics, Cryogenics is the study of the Production of Very Low Temperature (Below −150  °C, −238  °F or 123 K) and the Behavior of Materials at those Temperatures. A person who studies Elements under Extremely Cold Temperature is called a Cryogenicist. Rather than the Relative Temperature Scales of Celsius and Fahrenheit, Cryogenicists use the Absolute Temperature Scales. These are Kelvin (SI units) or Rankine scale (Imperial US units).

I remember sitting in my physics class when my phone buzzed and I received an alert from CNN about the tragic event. Newtown only being about 30 minutes away from where I live, affected my city greatly. The rest of the school year every elementary school in my district had a police officer stationed in front of it and my high school’s securityRead MoreThe Toulmin Model Of Argument 11533 Words   |  7 Pagesrelating to laws and policies that restrict the sale and use of firearms.) Claim of Definition: Laws governing the sale of firearms such as assault weapons and handguns do not constitute an infringement on our right to bear arms. (This speech/essay will focus on the Bill of Rights and its clause about the right to bear arms. It will argue for a particular definition that excludes the writing of laws that relate to ownership of firearms.) Claim of Cause: Tougher laws governing the sale of handgunsRead MoreForensic Science : A Forensic Scientist1546 Words   |  7 Pagesforensic scientist means that there is a high level of standard, considering that it will require a person to work with evidence and dead bodies.
