Lynch, Mary Partners: Hicks, Black; Kroeger, Erik; Carper, Mike Motion: Projectile Motion TA: Meghna Bhattacharya (Section 4) February 28, 2017 OBJECTIVE This object of the experiment was to demonstrate the average distance the ball traveled when shot from the spring gun. The test was used to show how the angle of elevation and initial velocity will affect where the ball is estimated to land. Using data collected on average distance found in part one of the experiment, you were then able to calculate
Projectile Motion Lab Introduction: The purpose of this experiment was to find how changing the angle and velocity would affect the distance the object went, height the object went, and time the object was in the air. Before this lab I could not tell how the angle and velocity would change the results. I needed to figure out what angle and what velocity made the object go farther or make it stay in the air longer. I also found mass will affect the height and distance. I used the site Galileo and
Investigating Free-falling Objects and Projectile Motions Aim: The aim of my experiment is to obtain results/ data and see whether a pattern can be distinguished or whether my data agrees with a theory or law. I'm going to try to undergo two investigations using the same apparatus, and look at the outcome of my results and see whether a firm conclusion can be made. For the two investigations, I'm going to look at free-falling objects and projectile motions: Investigation 1: Isaac
have had an assortment of purposes, but the most commonly purpose was to launch a projectile to destroy castles and soldiers. There were three main types of catapults; Ballista, Mangonel, and the Trebuchet. The mangonel was the most popular one. Different levels of torsion in the rope of the mangonel catapult decided how far a projectile was going to travel. Also the different objects that were used as projectiles and there masses also had a big role in the distance they would reach. If physics
Safe handling of firearms at crime scene. A high priority at a crime scenes safety in collecting the firearm. Preservation of evidence is essential. The firearm used to commit the crime may not be at the scene, cartridge casings and expended projectiles may be at crime scene and provide information about the type of firearm used. When a firearm is retrieved by a suspect it can be identified by distinctive tool marks on the expended casings, and individuals bullets can be linked to the firearm. By
is an electrically powered electromagnetic projectile launcher composed of a pair of parallel conducting rails, along which a sliding armature is accelerated by the electromagnetic effects of a current flowing down one rail, into the armature and then back along the other rail. The rail gun was created in 1918 by a French inventor, Louis Octave Fauchon-Villeplee. His original design consisted of two parallel busbars connected by the wings of a projectile, and surrounding the whole apparatus with a
unique similar striated and impressed markings. The examiners will also initially identify the class characteristics of the ammunition to figure out what caliber and shot pattern is dispersed by the firearm. That will then lead to examining the projectile and cartridge evidence by firing into a special water tank and cross examining the new standards to the crime scene standards. These standards are viewed side by side under a powerful macroscope to compare the unique markings to make a match.
calculations that govern the projection of objects such as a baseball. Through these calculations we will scrutinize the variables involved that causes this type of projection (Jenkinson 1996). First we will examine the primary factors involved with projectile motion in an ideal situation, where no air resistance is involved. These factors are: * Initial Velocity * Initial Height * Initial Angle * Gravitational Force These are the four primary factors. The initial velocity is the speed
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. These things are the drag of air on the bullet and the force of gravity acting upon the bullet. The force
development & suspects which made the viewer keep on guessing until the last scene. Case 2 was much complicated one. There was not more use of Forensic Science techniques rather than the GSR test. On one hand the physics being used to find out the projectile motion of the bullet was summarized within little time period made viewers a bit difficult to find out the things going on. Whereas the experiment performed in solving the unusual pattern of bullet shot was very interesting one. Though the story
did use it to make many important discoveries about astronomy, though; many of these discoveries helped to prove that the sun was the center of the galaxy. Galileo also made many important contributions to Physics; he discovered that the path of a projectile was a parabola, that objects do not fall with speeds proportional to their weight, and much more. For these discoveries, Galileo is often referred to as the founder of modern experimental science. Galileo Galilei was born in Pisa, Italy on February
consider them beautiful, artful displays of light. Either way you look at it, pyrotechnics is an interesting and dangerous hobby. Many colors and designs may be created by the placement of different compounds in distinct areas of the fireworks, either projectile or stationary ones. Some of the many different colors of the visible spectrum that can be easily recreated are; yellow, orange, red, green, and blue. The shades of yellow and orange can be easily recreated by the use of sodium or calcium chlorate
value of luck cannot be overstated. A bullet may leave the muzzle of a weapon at over a thousand feet per second and slam into a concrete wall. This may deform the round beyond all recognition. Just about anything can and does happen to flying projectiles.
An Interesting Short History of BB Guns Before beginning about the history of ball bearing or bullet ball guns, which are referred to as BB guns in short, let’s take a quick peep at some of the most interesting facts about air guns: 1. The first air powered gun came into existence in the 1950s. 2. Daisy, which is one of the most renowned air guns company, did not start out by manufacturing BB guns. It began its business by manufacturing windmills. 3. The first pneumatic gun was manufactured for Henry
idea of how it works. Two rails are electrically charged while sitting parallel to each other. The projectile connects the two rails together creating what is called Lorentz force. The result is an electromagnetic force that sets the projectile in motion at speeds of up to 5,600mph. The amount of power applied along with the size of the projectile help determine how far and fast the projectile will travel. The current aim for the Navy is an EM Railgun that operates at up to 32 mega-joules and
Introduction There are thousands of models of shotguns, who knows how to choose which one for the right job? The most common gauges of shotgun are 10,12,16,20, and 410. This experiment can test any of those gauges against each other, but the two that were tested in this experiment were the 12 gauge and the 20 gauge, as they are often compared for different jobs. If that’s confusing, don’t worry, it won’t be after this paper. Now, there is a ton of terminology involved with shotguns and
Examining Projectile Motion Introduction When I was younger, I’d always worry about not being able to reach an object or be able to score a goal in sports. Especially because of my short height, I’d have to find creative ways in order to achieve these things. Projectile motion is just a fancy way of describing the efforts I had to go through in order to throw a basketball into the hoop at a certain height, or hit a golf ball at a certain angle in order to aim it. Projectile motion is used in our
So you are into reloading and you wonder how well that little package with 77 grains of IMR 4350 powder behind a 300 grain round nose, full metal jacket bullet will do. Well, you can do two things, a little bit of physics calculations, or go out and touch it off, hoping that it doesn’t explode in the barrel! I would choose to do a little physics myself… By using some basic physics equations, you can figure out just about any part of the rifles ballistics data. For instance, if you know a few
smaller mass (m) (the projectile), was positioned on the end of the longer arm near or on the ground. In practice the projectile was usually placed in a leather sling attached to the end of the longer arm. However for simplicity, we shall ignore the sling and compensate for this omission by increasing the assumed length of the beam on the projectile’s side. The counterweight was then allowed to fall so that the longer arm swung upward, the sling following, and the projectile was ultimately thrown
history of ballistics dates all the way back to the 1800s. In the late eighteenth century, pistols and muskets were substituted with rifled weapons; bullets gained a distinct mark (Ramsland, 2014). Rifles had grooves made inside for more accurate projectiles, which meant that it would leave a specific mark on the bullet as it was shot each time (Ramsland, 2014). Any bullet fired from a certain type of weapon will have the same markings (Ramsland, 2014). Matching bullets to ballistics was first born
