Physics of Projectile Motion in Computer Games - Introduction Physics define the rules by which we live our physical existence. Many of us go about our day to day lives without any true understanding of the Laws which govern how we interact with our surroundings. Physics is our way of making sense of the forces which act upon us and shape the way we accomplish even the most menial of tasks. From walking to driving to playing a game of catch, anyone can see physics in action. A computer game programmer must take a special look at the forces at work around us....   [tags: physics video game computer]

Science Research: Projectile Motion and Arcs - There are many concepts in shooting including arc, backspin, projectile motion and trajectory. For my science project I was interested in learning if shooting from different starting places made a person more likely to make a shot. I think the most crucial element of a shot is arc. It is important for a person to have a medium arc. If their arc is to flat or to high it will be very challenging for them to score. Without a good arc players would not nearly score as much. One of the most important, and sometimes most overlooked techniques of shooting is backspin....   [tags: Science Research, Science, Research, ] 569 words

Physics of Rail Guns - The concept of a rail gun is simple: two parallel bars connected to a power source produce an electric field. This electric field can be used to propel a projectile along the bars. If enough amperage is provided, the projectile can achieve velocities of up to 4 km/s. The U.S. Army has been interested in the potential of electromagnetic guns for quite some time. In 1988 the University of Texas Center for Electromagnetics began work on a 9 MJ range gun, which would be designed to launch 2-4 kg projectiles at velocities of up to 4 km/s....   [tags: physics weapon weapons rail gun] 1213 words

Gauss Guns - The theory behind gauss guns is that you can take electrical energy and convert it to kinetic energy by using an electromagnetic energy storage field. In essence, you take a ferrous object (the projectile) and place it at one end of a hollow solenoid. When electricity is applied to the coils inside the solenoid, a magnetic field is generated which pulls the projectile towards the center of the coils. As the projectile reaches the center and continues, the magnetic pull decreases and eventually reverses....   [tags: physics gauss gun] 619 words

Physics of Catapults - The ballista, or "shield piercer," was first developed by the Greeks using the same principles as a bow and arrow. Its primary use was to, as the name suggests, pierce enemy shields, since normal bows lacked the power to do so. Early versions of the ballista include the gastrophetes, which is nothing more than an enlarged bow that can be braced against the users body. http://members.lycos.nl/onager/GastrophetesPic.jpg As time went on ballistas were improved to become larger and more powerful, eventually becoming mounted mechanisms that could be operated by two or more people....   [tags: physics catapult] 1136 words

Physics of Soccer - Physics of the Ball How and where you kick the ball is the most important aspect within the game of soccer. Lets say you kick the ball perfectly giving it no rotation (or spin), this means that you have given the ball a velocity (v) and an initial angular speed of zero. When the ball comes into contact with the ground it will begin to spin because the ground is not frictionless. The soccer ball will eventually begin to roll without slipping, which is when the balls center of mass is equal to its angular speed....   [tags: physics sport sports soccer football] 1400 words

Your foot, therefore, gives the ball an initial speed (v) and an initial angular speed of 0. Since grass is not frictionless, the ball initially slides across the field, then starts to rotate and, eventually, starts rolling without slipping. A soccer ball rolls without slipping when its center-of-mass speed equals its angular speed (around its center of mass). OK, now suppose you want to kick the ball so that it immediately starts rolling without slipping....   [tags: physics sport sports soccer football] 734 words

The Physics of Basketball - The Physics of Basketball Introduction Any child can pick up a basketball, bounce it a few times, and throw it at the hoop without realizing the complex physics he is involving himself in. However, a greater understanding of the sport can be gained by applying the principles of physics to these actions. Through this paper I will be examining the physics of dribbling and shooting. For the equations, I will use a standard men’s basketball with a mass of 25 oz. (0.7 kg) and a diameter of 9.39”. Dribbling If the basketball was simply dropped from a height of 1 meter with no initial push from the dribbler and rebounded from the floor in a perfectly elastic collision, Mechanical Energy for the system would be conserved (1)....   [tags: Physics Essays]

An Enigmatic People and Their Rock Art - An Enigmatic People and Their Rock Art Archaeologists often rely on material traits to define culture groups. In the Southwest, one such group, the Fremont culture, has to a large degree defied classification. Inhabiting an expansive territory in the northern reaches of the Southwest, the Fremont sometimes look archaeologically very similar to their neighbors, the Anasazi, and to groups living on the Plains and in the Great Basin. The origin and eventual demise of the Fremont culture has been the subject of much debate, as has the question of whether the Fremont even constitute a “culture.” More than any other term “variable” seems to describe the Fremont best....   [tags: Fremont Culture Archaeology Essays]

Location and Description of the Algonkian Indians - Location and Description of the Algonkian Indians - Algonkian lived in Quebec and Ontario; starting from the Ottawa valley, beneath Hudson Bay and above lower Ontario - the areas in which they lived in were dense woodlands with trees, such as, birch and evergreen; and snow covered the land most of the year. Adaptation to the physical Environment Home - Algonkian homes were called Wigwam, there frames were built out of saplings of tall, young tree trunks which were tied together with narrow strips of bark or root fibers, to form a dome shape - the frame was covered with woven mats or barks, then was firmly tied to the frames - light birch bark were used as covers in the summer and heavy elm or walnut bark was used in the winter Changing Climate - tribes lived in one designated location, but it was common for them to move within that region, depending on the season - during the spring and summer they would shift their homes closer to the water so that they may be able to fish with more ease - while in the autumn and winter they would move near the forest so they would be able to hunt for animals Transportation - on land Algonkians generally walked, but they traveled by canoes in the water - they had two types of canoes - the dugout and birch bark, which were made from hollowing whole trees Clothing - clothing simple yet sturdy - during summer men wore only a deerskin loincloth - women wore an apron or a long wraparound skirt made form the same material - when weather became colder the Algonkian added skin shirts, fur robes, leggings and feather clocks - they also greased the bodies to ward off insects in the summer and keep warm in winter Mode of Substance - Algonkians lived too far north and outside the rice ring for agriculture - they were mainly semi-nomadie bands of hunter -gathers - some southern bands began growing crops in 17th century - they hunted animals using the nich of projectile points made from flints - they were best identified for their skills as hunters who made the best traps and snares, the traps and snares come in many different forms and changed with each season - among the animals hunted were deers, moose, beavers, cariboues, elks and bears....   [tags: Algonkians Indians Native Americans Essays] 1219 words

Ballistics - In 1784, someone using a flintlock pistol shot Edward Culshaw. In those days, there were no bullets, as we know them. Gunpowder and a ball of lead were put into the gun’s muzzle and packed with paper wadding. A spark made when the gun’s hammer struck some flint at the back end of the barrel ignited the powder. When the constable examined Culshaw’s wound, he found a piece of newspaper used as wadding to pack the powder in the killer’s gun. The prime suspect in the killing was a man named John Toms....   [tags: essays research papers] 1789 words

They needn't really worry about this, because gravity generally keeps that sort of thing from happening. The thing is, no one is really sure what causes gravity, but the effects have been studied by many physicists and astronomers. Three of the more obvious effects of gravity are things falling down, weight, and the the moon and planets staying in their orbits....   [tags: essays research papers fc]

throwing a football - Throwing a football When the football travels through the air for a long pass it always follows a curved path because the force of gravity influences the movement of the ball in the vertical direction. As the ball travels up, gravity slows it down until it stops briefly at its peak height; the ball then comes down, and gravity accelerates it until it hits the ground. Projectile motion is the path of any object that is launched or thrown and has an arched course (howstuffworks) For the football to travel the most accurate and furthest distance, the ball must have the tightest spiral it can develop....   [tags: essays research papers] 647 words

They both describe about the terrors of war and the suffering of each side's men and what they had to go through. The two different poets have very different views on how the war actually progressed. The first poem "The Charge of the Light Brigade" is a piece of propaganda for the army; similarly for "Dulce Et Decorum Est."
