Research and Background A pendulum is an object hanging from a fixed point with a mass that swings back and forth under the influence of gravity. Sometimes this mass is called a bob, as it bobs up and down as it swings side to side. Pendulums are acted upon by three main forces: gravity, tension, and air resistance. While gravity always pulls down on the bob, tension pulls upward towards the pivot point for the string on the rod, or where the string pivots. However, both the amount and the direction of the pendulum’s tension changes as it swings. When the pendulum swings left of its equilibrium position, or the place where the pendulum comes to rest, gravity is still acting downward, but the tension is acting towards the pivot point, so it …show more content…
I would make two changes to the setup. The first change would be to instead of having people drop the pendulum and record the period, robot’s would perform the task. Robots would allow the experiment to be fully automated, and will ensure that there is no chance for human error, allowing the data to be accurate and precise. I would also change where the protractor is placed. Instead of having it taped the bottom of the string, I would place it towards the top where the string pivots on the rod. If a protractor is placed towards the bottom of the string, when lifting the pendulum to a certain drop angle, it won’t really drop from that angle, as only a certain part of the string is dropping from that angle. Placing the protractor higher will allow the drop angle to be more accurate. After testing the pendulum with the different variables, we found that the only variable that seems to change the period of the pendulum is the length of the string. This is because the longer the string length of the pendulum is, the longer it has to swing, resulting in a longer period of the pendulum. When we performed the control experiment with 70 cm, of string, the average period was 1.68 seconds. When we tested the period of the pendulum with only 40 cm. of string, the period of the pendulum became 1.25
For each test, I was required to calculate the height of the pendulum required in order for it to have the same mass, or the quantity of matter affected by the external force of gravity, as my project. To find the height, it required understanding the process of the pendulum hitting my project step by step. As the pendulum is pulled back, it has its maximum potential energy, which is the energy possessed by a body by virtue of its position relative to other objects. When the pendulum is let go, it loses potential energy while gaining kinetic energy, or the energy that a body possesses by virtue of being in motion. At the bottom of the swing, kinetic energy of pendulum is the greatest because the change in potential energy equals the kinetic energy at the bottom of the swing. As the pendulum hits my project, there is an impulse, a force acting briefly on a body and producing a finite change of momentum, between the pendulum and project. As the pendulum hits my project, the project carries the momentum of the pendulum with it. By working in reverse order, the height of the pendulum required was
After evaluating the 2081 movie, it is apparent the film elements and techniques are important when defining the mood. The four main techniques used throughout the film were lighting, music, sound, and dialogue.
The Bible was one of the most important pieces of text during Galileo’s lifetime. If you went against what the Bible stated then you were considered to be a heretic. The Bible indicated that the earth was in the center of the universe and the sun and the other planets revolve around it. a theory known as the geocentric model. Many scientists argued against this theory by stating that actually the sun was in the center of the universe and the earth and the other planets revolved around the sun, this theory was known as the heliocentric model. Nicolas Copernicus was one of the first out of many scientists who publically shared this theory. Later Giordano Bruno also supported this theory and because of this the Church ordered him to be burned
On September 11th, 2001 at the World Trade Center 2,749 people were killed when hijacked American Airlines Flight 11 and United Airlines Flight 175 were crashed into the north and south towers. 412 of them were rescue workers who came to help. 147of them were passengers or crew members on the two flights. 102 Minutes by Jim Dwyer and Kevin Flynn, the title referring to the time between when the first airplane hit the north tower and the south tower collapsed, tells the stories of what is happening inside the Twin Towers on September 11th and the fight for survival under unimaginable conditions.
Have you ever watched a movie and been dissatisfied, because it was not similar to its book? There are multiple movies that seem as if they are their own story, for they don't resemble their book at all. For example, “The Pit and the Pendulum.” by Edgar Allen Poe. He, himself would not approve of the film that follows his story. For one thing, the storyline was no where near to being like his book. Another reasoning is that he wrote based of one man not multiple people. And finally, he wouldn’t of approved of the art on the walls in the room with the pit and pendulum. These are the reasonings of why Poe would not appreciate the film.
There are many ways in which scientists and researchers try to understand the molecular uniqueness and physiology of living organisms. One of these ways is the Circadian clock, this clock transfers the physiology and behaviors of mammalians into rhythms that are coordinated with the 24hr solar system. This system can be affected by environmental factors such as the food, temperature and parasites. The circadian rhythms play a role in gene expression to produce protein. Gene expression is displayed through the central dogma of (DNA RNA protein). How the clock work with the 24hr solar day is that it allows gene expression every 24hr to tell when a physiological process is most active. And any damage made to the DNA is more effective
Both passages concern the same topic, the Okefenokee Swamp. Yet, through the use of various techniques, the depictions of the swamp are entirely different. While Passage 1 relies on simplicity and admiration to publicize the swamp, Passage 2 uses explicitness and disgust to emphasize the discomfort the swamp brings to visitors.
In the United States of America, there once was this dance that evolved in a slave state known as South Carolina, Charleston, and a dance called Argentine Tango that evolved in america after being brought into the nation through global expansion. Both of these authentic dances exemplify a specific movement of techniques that gives the dance its power and name. Tango gives us a sensational feel that articulates adequate movements and creates richer, profound appearance. The Charleston dance brings out the joy in people that allows a person to let loose and be free. Both of these dances has been brought out into other countries. For example, the Charleston dance first originated in South Carolina and then made it around to other countries where
The body and brain are changing machines, where states of consciousness shift with zealous nature to allow our human anatomy to flourish. Schedules of the circadian rhythm function differently for everyone yet, is an important part of functioning for the human anatomy/mind. For the average person, however, the cycles we go through usually speak for a sleep rotation. But sometimes, even with these measured rituals, we find ourselves at a loss when we realize how fragile our circadian rhythm can be, caused by "insomnia," " jet-lag, " or even "weekend-lag."
“I Stand Here Ironing” by Tillie Olsen, is a story about a mother's struggle to balance the demands of raising children and having to work to make ends meet during the Great Depression. The story’s primary focus is on the relationship between the narrator, a mother, and her first child, Emily. Throughout the story, the narrator reflects on the decisions and mistakes she made while raising Emily. The narrator was detached from Emily almost completely during her younger years, but she desires an emotional connection to her, like she has with her other children. She also wants Emily to have a better life than she had.
This condition can be treated various ways depending on “the type and frequency of arrhythmias, associated symptoms…, and the presence of structural heart disease” (Cleveland Clinic, 2014). Some patients may not need treatment at all, since they show not symptoms, since sometimes this condition can be naturally eliminated over the first year of life, but may still be required to have regular schedule appointments with the physician so the patients can be monitored. If symptoms are prevalent, the different treatment methods include a pacemaker, defibrillator, surgery, and medicine.
Historically, Gallileo Galilei had a multitude of identites. To the Catholic Church he was a heretic. To religious reformers, Galileo was bastion of truth and chapion of the the individual. But who was galileo, in his own mind? It may be impossible to determine what the historical Galieo thought of himself; however making inferences and even creating and entire identity from what is known about the man can be a fruitful journey into the human soul. The is exactly what German Dramatist Bertolt Brecht has done in his laudable play "Life of Galileo." This recreation of Galileo depicts his struggle to find his place within the tumultuous atmpsphere of the fledgling Italian Renaissance. As the play progresses, the audience witnesses Galileo being pulled between established authourity of the church and rising influence of free thought. However even he cannot eslcape the influence of the church, the most powerful and pervasive gonverning body of the era.
The word tango is most likely from African origin and referred to popular music and dance celebrations that the slaves performed throughout the Caribbean and Atlantic coastal regions. The genre overlapped with milonga, candombe and the Cuban habanera. During the 20th century, around the time that the urbanized samba emerged in Brazil, the tango emerged as an independent dance genre. The rioplatense tango arose in poverty stricken areas known as arrabeles in the outskirts of Buenos Aires and Montevido. The compadrito was a quintessential early figure that emerged out of the arrabales; his dress and behavior mocked the elite, posing as an arrogant bully. He blended gaucho and immigrant characteristics and spoke lunfardo (a dialect with references to the criminal underworold). Most people considered him vulgar and disreputable but many secretly admired his provocative sensuality. The first stage of tango history is known as Guardia Vieja and lasted until 1920. During the period, the tango emerged as a genre of instrumental music based on a three-part form with different sections. The Guardia Veja ensembles had one violin, flute, guitar, and bandoneón (an accordion-like instrument of German origin associated with the tango that is also used in contemporary traditional music ensembles. It has 38 buttons in the upper and middle registers and 33 buttons in the lower register. What is argued to be the most famous tango ever written was “La cumparsita” (“The Little Carnival Procession”) by Gerardo Matos Rodriguez in 1917. Early tangos used rhythms related to the habanera and milonga in duple meter, but bandleaders began to slow the tempo and adopted a quadruple meter with sharp accents during the 1910s. The marcato and sincopa characterize...
When tragedy strikes, it is normal for individuals to go through stages of grief. In some situations, people become cemented in one stage of emotional instability. They focus so much on their anger over the inevitability of the unfairness of life, that it eventually makes them go mad. This theme composes the synopsis of Joyce Carol Oates’ book We Were the Mulvaneys. The rape of Marianne Mulvaney catalyzed the disembowelment of the Mulvaney family due to their inability to move on from their grief; each family member coped in unique manners.
