Lab Report On Projectile

Air trajectory is the physics of how an object moves through a “fluid” which can be a liquid or a gas. In the event of Air Trajectory, students launch projectiles a certain distance using gravitational energy in the form of a dropping weight. The involved science is more about the most efficient method of launch rather than how the projectile moves through the air.

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

The project of the railgun was initiated in 2005. The goal of phase one is to show

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.

Medieval weaponry is divided into two classes, cold weapons and firearms. A cold weapon is a weapon that does not involve fire or explosions. Swords were the most common cold weapon. They were used to pierce through armor, and deliver a deadly blow. Knives were used to finish a kill. They were carried in a holster on the hip of a warrior. Spears were used on horse-back and on foot. Warriors would throw spears at enemies if they were out of range of a sword. A catapult was as deadly as a firearm, but not considered one. Catapults would fling rocks at enemies over a distance. Like a catapult a crossbow could strike from a distance. Crossbows shot arrows that could pierce armor. Cannons were the first firearm introduced around the 14th century. They shot balls of molded

Ever since the development of the first few examples of rocket power, it was evident that this was technology that was going to change the face of the world forever. Since missiles and other weaponry were now able to be launched across continents and even oceans, it made the world feel a whole lot smaller. In turn, this was the technology that “had its ultimate foundation in the simple power rocket which originated as a weapon of war” . However, this technology underwent an extreme transformation over time and was eventually the basis of the technology used to put spacecrafts up in space. One of the main rockets that is going to be discussed in this paper is the V2 rocket designed by the Germans during World War II, as much of the technology that put spacecrafts in space came from this rocket. Another aspect that is going to be

Some of these factors are gravity, the air resistance, the speed of release, the angle of release, and the height of release. The most basic and principal factor acting on a projectile is gravity. Gravity affects every object. It decreases the height that a projectile can attain. Air resistance is also a key factor working on an object. The larger the surface area, the more air resistance will affect a projectile. Air resistance will also affect an object more if it has a smaller mass. Also, the faster the speed of the projectile, the greater the air resistance. The speed of release refers to how fast an object is released and is directly related to the distance of the flight. The greater the speed of release and object has, the greater the distance the object will have. The initial vertical velocity increases the height of trajectories, creating a longer flight path. Similarly, as the initial horizontal velocity increase, the longer the length of flight and distance. The angle of release is the angle that an object is thrown or hit into the air. It changes the relationship

Solid shot was a kinetic energy round. Its speed and mass were used to penetrate walls, fort and armor. To produce any type of casualty effect, the round would have to actually strike the target. Solid shot was particularly used against ironclad ships where a shell would do little or no damage. During one test an 8 inch Brooke rifle with 16 pounds of powder fired a 140 pound ball 260 yards and penetrated eight inches of iron backed by 18 inches of solid wood.

“This variation has a design of a smaller breach that fired a cartridge of 76.2x585R, allowing a breach that will automatically open after the firing of each cartridge” (Ordnance, T. O, 1920). This was an innovative concept that allows the firing of multiple rounds at a greater rate to help with the adjustment needed when firing at an aircraft traveling at a high velocity, attitude, and altitude. “The muzzle velocity of this weapon firing a 15-pound shell, with either shrapnel or explosive charge, is 2,400 feet per second” (Ordnance, T.O, 1920). The maximum

The Catcher in the Rye has been long wrung out and decoded, since its arrival on the scene of long-listed literary masterpieces. Every detail, every word and phrase has been carefully placed under a microscope by a scholar in hopes of finding an untouched pattern. The common motifs throughout the novel represent ideas of oneness and isolation, being the catcher and the caught, and the vital representation of foundational opposing binaries. This duality configuration places an air among those who live today; it becomes a fact all must face at one point or another. Of course, one may argue that the choices of opposite binaries does not, in fact, have to place a role in human nature and one may choose an optional gray area, but what is that gray

The sketch below shows the trajectory of a projectile propelled with an initial velocity V0 at an angle 8. Neglecting air resistance the horizontal range travelled is given

(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

In this experiment, I will be learning about the ballistic penetration properties of different soils. My hypothesis is: If I shoot a container of sand, then that container will have the least amount of penetrative impact. I thought that this outcome would be likely, because sand is dense and coarse, making the bullet halt. While thinking of experiment ideas with my dad, he mentioned this project. I thought this would be a fun project to do, because I have always liked thinking of how you could make something with more local products.Throughout the course of this paper, I will be explaining the properties of the concertainer, HESCO, and some bullet resistant materials relevant to my experiment.
