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 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]

Projective Testing - Projective tests are a measure for analyzing personality. They are established in the idea of Sigmund Freud’s theory of unconscious processes. Projective techniques were first sought out as a means for people to unconsciously project their personality on to obscure or vague stimuli, possibly revealing the patient’s internal conflicts and hidden emotions. Projective testing has been found to significantly differ from other objective psychological tests through the range of possible responses making them difficult to standardize and evaluate (Trull, 2005)....   [tags: Psychology]

Vectors And Projectiles - Vectors And Projectiles After successfully completing the first two videos of the Paul Hewitt series, I have been drawn to this course. The third video of the series reviews the concepts of vectors and projectiles. In this video Paul goes over a lot of previously stated formulas. The ideas of how fast or hoe far an object travels are restated. The idea of how fast an object travels is known as its velocity. The velocity is found by finding how far an object travels over a period of time. It may be easier to multiply the pull of gravity, which in a free falling object is ten meters per second accelerating, by the seconds the object remains it the air....   [tags: Free Essays] 398 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

From Aristotle to Newton: The Development of Modern Physics - ... Aristotle proposed that projectiles were kept in motion by the air displaced through the projectile’s path. The propellant, then, would be the medium through which the projectile passed, since there was no apparent force to counteract the force of gravity. The theory of impetus was put forth initially to explain the phenomena of projectile motion against the force of gravity. This theory states that impetus is a kind of invisible power that propels objects forward and can be imparted on an object by another object or the medium through which the object is traveling....   [tags: Galileo, Scientific Method, Scientific Discoveries] 1597 words

Since the charge and projectile were loaded into the rear of the barrel, these were called breechloaders. The breechblock was mated to the barrel by means of a recessed lip at the chamber mouth. Before firing, it was dropped into the stock and forced forward against the barrel by hammering a wedge into place behind it; after the weapon was fired, the wedge was knocked out and the block was removed for reloading....   [tags: Papers] 890 words

Physics of Fireworks - After black powder was discovered by the Chinese in the 9th Century, the relatively short history of fireworks began with this explosive chemical composition. Black powder is made up of potassium nitrate, sulfur, and charcoal (KNO3); in the correct amounts, this combination has very explosive results. The use of black powder sprung forth the evolution of muskets, rockets, and fireworks. Although history has shown that the development of black powder muskets into modern day guns, artillery, and weapons of mass destruction have changed the face of the earth, taken many lives, and changed the outcome of many wars, black powder is also used in many rituals and celebrations....   [tags: physics firework fireworks] 2865 words

Heart of Darkness - Heart of Darkness Life in London set a cushion for its citizens, “with solid pavement under your feet, surrounded by kind neighbors ready to cheer you or to fall you, stepping delicately between the butcher and the policeman, in the holy terror of scandal and gallows and lunatic asylums.” On the other hand, once a man enters the Congo, he is all alone. No policeman, no “warning voice of a kind neighbor,” -- no one. Joseph Conrad’s Heart of Darkness sets Marlow on a journey in the Congo, where he realizes the environment he comes from is not reality, but an illusion hiding true human nature....   [tags: essays papers] 1122 words

Ecological Imperialism: The Biological Expansion of Europe - Ecological Imperialism: The Biological Expansion of Europe, 900-1900, by ecological historian Alfred W. Crosby explores how “portmanteau biota”, helped Europeans to eradicate whole societies in the Neo-Europes (xv, 89). Crosby believes that temperate zones, climates similar to that of Europe, allowed European biota to thrive, which allowed for European expansion. Crosby discusses the Norse invasions and the Crusades as examples of how Europeans were not able to expand. Crosby claims that climate was crucial to European expansion because it allowed portmanteau biota to thrive....   [tags: Alfred W. Crosby] 844 words

The Battle of Dunkirk: A Tactical Defeat - The Battle of Dunkirk happened in Northern France between May 26 and June 4 1940 and was a major battle of the Second World War which occurred between 1939-1945. The Second World War was very different to the first with rapid movement covering huge amounts of land in very little time. This was due to the German Army’s speed which used “Blitzkrieg” or “Lightning war” tactics. Prior to the invasion of France there had been 7 months of “Phoney war”; However the French had anticipated the attack and established “The Maginot line” which was a line of defence designed to hold the German army back....   [tags: World War II] 1618 words

Women in Ministry and the Redemptive Trend Hermeneutic: My View - In 1988, the Council for Biblic¬al Manhood and Womanhood published the Danvers Statement, affirming that "In the church, redemption in Christ gives men and women an equal share in the blessings of salvation; nevertheless, some governing and teaching roles within the church are restricted to men." I am hesitant to single out one organization for focused argument, but this statement accurately represents a sentiment within the faith that I find disturbing. In this paper, I will use the redemptive trend hermeneutic to deconstruct the CBMW's affirmation, while providing my own views on why I find both women in ministry and the redemptive trend hermeneutic as valid....   [tags: Theology]

What Were the Effects of the Rifle? - The rifle was an extremely effective advancement in military history. The rifle has been used for centuries because of its effectiveness, shooting bullets straight and accurate because of the aerodynamics and physics of the spiral motion with the bullet. What makes the rifle a rifle and much better than a musket, is the fact that it has rifling throughout the barrel of the gun. Rifling is a system of spiral grooves in the surface of the bore of a gun causing a projectile when fired to rotate about its longer axis (Merriam-Webster)....   [tags: Military History]

Tornado - Tornado When a tornado forms or passes over a water surface, it is termed a waterspout. Like tornadoes, they may assume many shapes and often occur in series or families. Measurements of their forward speeds are scarce, but estimates vary from a few kilometers an hour to as high as 64 to 80 kilometers per hour. Contrary to popular opinion, a waterspout does not "suck up" water to great heights; though it may lift the water level a few meters.

Physics of Baseball - Finding and understanding the sweet spot on a wooden bat. When you strike a bat against a ball it sends vibrations, much like the vibrations acting on airplanes or bridges, which travel in waves through the bat. This motion is important to understand because every vibration the bat experiences takes energy away from the ball's speed as it leaves the bat. If you hit the ball at a bat's "nodes", the frequencies (each bat vibrates at several low and high frequencies at once, which is like the harmonics of stringed instruments) cancel out and since this happens you don't feel the sting in your hands that you experience when you hit the ball at different points on the bat....   [tags: physics sport sports baseball] 630 words
