• Momentum - 614 words
Momentum Abstract Measurements of velocity and mass of two objects colliding, support the conservation of linear momentum. The dynamics of different masses distinguish velocity values experimentally. Video recordings of two colliding masses can be manipulated to extract frames displaying distance verses time. Computer software enables us to derive the velocity. Different masses were tested to determine an increase, decrease, or equal effect. From this data, we ultimately derive the momentum of each cart and test the Law of Linear momentum. The following trials were measured: 1. An elastic collision with a cart moving at constant speed with a cart of equal mass originally at rest; 2. An elast ...

• Momentum - 430 words
Momentum Conservation of Momentum Kristin Favreau October 26, 1999 Purpose: To show that momentum is conserved in a closed system by illustrating the conservation of momentum in an elastic collision and an inelastic collision. Method: If momentum is conserved in a closed system, the total momentum of the system before collision should equal the total momentum of the system after the collision. Strobe photos will be used in the calculations that will prove that momentum is conserved. 1.) Elastic collision: A strobe photo will be used that shows a large glider smashing into a smaller glider which is initially at rest. This will cause the smaller glider to move and the large glider will continu ...

• Momentum And Collisions - 605 words
Momentum And Collisions This report will investigate the theoretical velocity of a ball bearing gun. The methods and techniques used to derive the results will be shown along with the possible systematic and random errors caused by experimental limitations. Discussion: Since the track is virtually frictionless and air resistance is neglected, the system is isolated; the net resultant force of the external forces equals zero. The total linear momentum of the system before the collision is equal to the total momentum after the collision. Therefore, the total change in momentum of this two-particle system is zero. Equation that represents the conservation of momentum: The total linear momen ...

• 16th Century English Weapons - 1,456 words
16th Century English Weapons 16th Century English Weapons During the 16th century England and much of Europe found itself in turmoil and in a constant state of war. The outbreak of fighting led to the invention and development of new weapons and the growth and change of weapons of old. The development of weapons was a trademark of the time, with a sort of renaissance, or re-birth in the field of weaponry (Miller). The technology was highlighted by the invention of gunpowder by the Chinese which eventually found its way to England (Grolier). However, the use of gunpowder was minimal, because the use of had yet to be perfected. The technological advancement most useful during the period was pr ...

• A Personal Information - 1,287 words
A. Personal Information Arthur Kornberg (1918-), American biochemist and physician, claims he has never met "a dull enzyme." He has devoted his life to pursuing and purifying these critical protein molecules. His love of science did not spring from a family history rooted in science. He was born on March 3rd, 1918, the son of a sewing machine operator in the sweatshops of the Lower East Side of New York City. His parents, Joseph Aaron Kornberg and Lena Rachel Katz, were immigrant Jews who made great sacrifices to ensure the safety of their family. They had fled Poland, for if they had stayed, they would have been murdered in a German concentration camp. His grandfather had abandoned the pate ...

Affirmative Action The state shall not discriminate, or grant preferential treatment to any individual or group on the basis of race, sex, color, ethnicity, or national origin in the operation of public employment, public education, or public contracting. The previous statement is the unedited text of the operative part of Proposition 209, the California Civil Rights Initiative (CCRI), that passed November fifth by a percentage of 54 to 46. Though the initiative does not actually mention affirmative action, Californians feel affirmative action may be coming to an end. Will the decision of Proposition 209 have a great impact on colleges and universities? We will soon find out. We do know that ...

• African American Heritage In Chicago - 702 words
African American Heritage In Chicago A History of African American Heritage in Chicago The massive exodus to the north began in 1915; a population of people weary of pervasive hostility and constraint in their former lives, fleeing a social system comprised of miserable oppression and repeated violence. The primary cities for resettlement became New York and Chicago, metropolises humming with the vigor of big-city life and the excitement of a new beginning. When the Chicago Commission asked African American migrants in interviews on Race Relations in 1922 why they came to Chicago, responses were similar. Im looking for better wages. I wanted to get away from the South, and to earn more money ...

• Ahl Finals - 820 words
AHL Finals When the Rochester Americans started the AHL finals, they were looking to add to their sixth Calder Cup banner to the ceiling. To get to this feat, they would have to go through the Portland Pirates. For teams making the playoffs, all teams start fresh and every team has a shot to win it all. This year's finals, is true of that last sentence because both teams had losing records for the regular season. When the playoffs arrive, that's the sign that the best hockey is yet to be played. When the Rochester Americans skated into the first two games on home ice, they had a chance to leave Rochester with a two game to none lead. They won the important first game 5-3 and won the second g ...

• Air Quality - 1,726 words
Air Quality Air Quality & Dispersion Today, the air quality aspect of ARL research is by far the dominant theme, but distinctions among the themes remain somewhat vague. For example, the models developed for emergency response purposes are among those used for air quality prediction. The Air Quality and Dispersion theme is one of the strongest ties that binds ARL's components together. ARL is not heavily involved in the pure science of the business. Instead, ARL focusses on the need to assemble integrated understanding and models from all available sources, to develop the capability to predict changes in air quality that will follow changes in emissions, or that will occur as a result of met ...

• Although Musicians Had Been Recording Fiddle Tunes Known As Old Time Music At That Time In The - 4,440 words
Although musicians had been recording fiddle tunes (known as Old Time Music at that time) in the southern Appalachians for several years, It wasn't until August 1, 1927 in Bristol, Tennessee, that Country Music really began. There, on that day, Ralph Peer signed Jimmie Rodgers and the Carter Family to recording contracts for Victor Records. These two recording acts set the tone for those to follow - Rodgers with his unique singing style and the Carters with their extensive recordings of old-time music. Jimmie Rodgers Known as the "Father of Country Music," James Charles Rodgers was born in Meridian, Mississippi on September 8, 1897. Always in ill health, he became a railroad hand, until ill ...

• American Women During World War Ii - 1,808 words
... ing the war years for many men hoped that marriage would defer conscription to the war. This alone suggests that women's roles as wives and mothers were still dominant during the war because the nation witnessed a 25 percent rise in the population aged five and under. The popularity of marriage and the traditional gender roles that marriage carried, was exploited during the war. For example, the Office of War Information, established in the summer of 1942, worked closely with the media. President Roosevelt soon denied the OWI was being used for propaganda , yet only months after the OWI was formed, wartime propaganda began to likened women's war work to domestic chores.

• Argentina - 1,023 words
Argentina For my case study on demographic transition Ive chosen the well-known country of Argentina, which is located in South America. I decided to conduct my study from 1936 to 1960. For this 25-year period I found all the statistical data which I need to actually complete population growth analysis. In the demographic transition model of Argentina we can see that the crude birth rate (CBR) is almost always double or higher then the crude death rate (CDR). This allows the natural rate of increase (NRI) to be higher than the CDR. NRI reflects how fast population is growing. In the demographic transition model of Argentinas CBR per 1000 (blue line) is the highest line relative to the origin ...

• Athens And Sparta - 855 words
Athens and Sparta Athens and Sparta The country of Greece in 400-500 B.C. was led to greatness by two great city-states. These city-states were Athens and Sparta. These two states were as different as night and day. They were rivals and very diverse. As you read you will find out their differences between their form of culture and government. The city-state of Athens adopted a form of government which is now called democracy. Democracy is when the government is ruled by the people. This government consisted of an assembly , a jury , and there was a council of 500 men over 30 . The council decided such matters as to declare war or to spend money. The council was used to make decisions for the ...

• Battle Of Shiloh - 951 words
Battle Of Shiloh The Battle of Shiloh After taking Fort Donelson, Ulysses Grant had wanted to move on the Confederate base in Corinth, Mississippi, where Albert Sidney Johnston, the Confederate commander in the West, was known to be assembling troops. Grant was ordered to delay his advance until Union General Don Carlos Buell, who had been operating in East Tennessee, could join him. Early on April 6, 1862, Johnston's army, which had come up to the federal lines undetected, struck Grant's army, which was encamped at Pittsburg Landing on the Tennessee River. The Battle of Shiloh followed. Grant's Federal army was not fully prepared for the thousands of screaming rebels who burst out of the wo ...
