Projectile Motion Lab: Using a Toy Gun

A firearm is one of the weapons that may be used when hunting. A firearm utilizes pressure produced from the burning of gunpowder to create gas. The pressure produced from the burning powder propels a projectile out of the barrel at a target. In rifles and most handguns the barrel has rifling on the inside of the barrel to make the projectile spin to travel better in the air. Rifling are groove that spin as they go through the inside of the barrel. Shotgun barrels are smooth and can fire “slugs”, a single projectile, or “shot”,

An investigation involving a firearm is a specialty of forensic science which focuses on the examination of firearms linked to ballistics. Ballistics is related to finding out the exact flight path of projectiles. Ballistics is the area of study that examines the exact path of the bullet from the moment it leaves the muzzle of the firearm up until it hits the target. During examination many items are collected for evidence including the firearm, bullets, live ammunition, cartridge casings, trace materials such as powder residue, and anything damaged by the projectile. Firearms are often divided into three processes: Internal, External, and Terminal Ballistics. Internal refers to the inside of the firearm; the space of time in which the shooter pulls the trigger, and the when the bullet is exiting. External ballistics is the flight between leaving the muzzle of the firearm, and it striking its target. Terminal ballistics is the impact of ballistics that refers to the examination in which the projectile strikes a target. All firearms leave markings on the cartridge casings once expelled when firing. Ballistic identification and microstamping laws make it possible to link a cartridge recovered to the

There are three types of artillery used by the Continental Army, which consisted of cannons, mortars, and howitzers. The two main types of cannons are the field gun that was lightweight and mobile, while the heavy siege gun is larger and has limited mobility. The field gun fired a variety of rounds such as solid shot, grapeshot, and canister shot that has a flat trajectory. This would tear large holes in the opposing forces ranks, destroying personnel, and equipment. Solid shot was simply a solid cast-iron cannonball that had the least effective range unless it was rolling or bouncing. Grape shot was most commonly used for long range target with a kill zone of 600 yards. Grape shot was generally constructed out of a canvas bag, with lead or iron balls half the size of musket balls that has a wooden base, and center rod to help the artillery men handle the rounds. Canister shot is a thin metal cylinder filled with a massive amount

A bullet is traveling at its fastest speed when it leaves the barrel of the gun. Bullets traveling after firing is said to be using kinetic energy. Kinetic energy is the energy the bullet has due to its motion from the firing pin striking the gun powder causing an explosion that forced the bullet to discharge from the barrel. Now this bullet possess kinetic energy and will do harm

A Rifle could shoot a bullet up to 1,000 yards–and were more accurate. However, until the 1850s it was nearly impossible to use these guns in battle because, since a rifle’s bullet had roughly the same diameter as its barrel, they took too long to load. (Soldiers sometimes had to pound the bullet into the barrel with a mallet.)

The sniper brushes with death again when he throws his revolver down without thinking and it goes off. Bullets make a war very deadly, as they are much more precise than earlier and much simpler weapons (such as swords and muskets).

In wars prior to the Civil War, soldiers wielded weapons such as the musket which shot only one bullet at a time. Though these types of weaponry could shoot as far as 250 yards, they were inconvenient and wasted time. To even aim at the target accurately one had to be 80 yards away. Similarly to muskets, rifles were inconvenient because they took a while to reload because the bullet was almost the same size of the barrel and again, wasted time. Bullets with a pointed tip were created in 1848 by Claude Minie. Because the diameter of the bullets were smaller than the barrel, soldiers could put them into the gun quicker and more effectively. With Minie’s bullets, rifles were simpler to reload but still had to be reloaded with one bullet at a time. That unprotected gap of time made soldiers more vulnerable so in 1849 a repeating rifle called the Volitional Repeater was patented by Walter Hunt. They were popularized in 1863 during the Civil War. By this time many models were being sold but the most common one was the Spencer Carbine which could shoot seven bullets in just 30 seconds. These, like most Civil War era weapons, were produced and used by the North, but not

The development of the rifle (a firearm with grooves along the inner barrel) meant a soldier could easily hit an enemy from hundreds of meters away, rendering

Although, the Glock is famous, it still needs the proper ammunition. As indicated in Campbell’s article, I also experienced the difference between poor and quality ammunition as well as reloaded. The quality impacts an officer’s confidence and shooting record. Although the situation was saved due to quality ammunition, hand-loads aren’t incompatible. Certain rules need to be adhered to in order to; function properly, save money, have specific tolerances to avoid overpressure and avoid blow ups.

There are 3 Laws of Motion developed by Isaac Newton in 1687, in his book “Mathematics Principles of National Philosophy”(Hall,Nancy).Newtons first law of motion says that an object will stay at rest until a external force is applied. Also know as inertia(Hall, Nancy). Gravity affects it buy pulling the counter weight down which pulls the the opposite side which has the sling and projectile up launching the projectile(Saimre tanol). For gravity to be most effective the counter weight must be at least five times heavier than projectile(Saimre tanol). Centripetal force is a big factor in calculating trebuchet factors. the definition of centripetal force is a force that acts inwards on any object that rotates or moves along a curved path and is directed toward a center point(Centripetal force). In this case centripetal force is good. when the projectile is released centripetal force pulls it inwards which makes it go farther and be more accurate with out centripetal force the projectile would go straight up or straight down(Centripetal

When the constitution was written the most advanced gun only shot one bolt at a time, and took 30 seconds to reload (Murphy). Now in the 21th century guns have “high-capacity magazines were used in at least 50% of the 62 mass shootings between 1982 and 2012. When high-capacity magazines were used in mass shootings, the death rate rose 63% and the injury rate rose 156%. David H. Chipman...stated that a high-capacity magazine ‘turns a killer into a killing machine.’ Some gang members use high-capacity magazines, such as 30 rounds or even 90 rounds, to compensate for lack of accuracy and maximize the chance to harm” (“Background of the Issue - Gun

When the speed of the ball increases to 100 mph or more, the launch angle goes up by two or three degrees until there’s an exit velocity of 116 mph. At that point, a ball with a launch angle of eight to 50 degrees is classified as barreled.

In light of our final exam, the chuck a duck project, we are to learn about projectiles, trajectory, and the factors that affect these things.

To inspect what the problem is, he utilizes some inert rounds (dummy) in order to check the feeding. As he is working with this weapon, a shell falls out from the bottom while pumping the shotgun. Immediately he suspects he cartridge stop being the culprit. On the underside where you load the shells, he shows the viewer the two plates facing opposite. One is the primary cartridge stop, and the other is secondary. One holds the shell, and as you pumo, the primary disengages, and the secondary cartridge stop pops out, and holds the cartridge (in the tubular magazine I'm assuming). The corrective action for this to replace the primary cartridge stop. It can be anything from a simple bend, to as bad as needing to completely replace the part.

(Melvin, Mangonel - “Physics of Catapults”) The speed and distance of the projectile depended on how much force the catapult applied to the projectile, and the momentum depended on the mass and the velocity of the projectile (dead diseased cow, or flaming
