... The distance in which the ball falls will be measured. The equation, d=1/2gt² describes a body starting from rest and undergoing constant acceleration; d is the distance, g is the acceleration and t is the time. Acceleration is equal to distance doubled divided by time squared, g= 2d/t². Two different sized balls will be used in this experiment to calculate the acceleration. CONCLUSION The acceleration was successfully calculated to be 0.4104m/s² for the 0.017kg ball and 0.4032m/s² for the 0.028kg ball. The ball with less weight travels slightly faster than the ball with heavier weight. The time pad measured the time it took for the steel ball to fall upon manual release from a certain height (distance). There is a 95% difference between the calculated acceleration and the accepted value. Different mass and size of the objects can affect gravitational acceleration. Possible sources of errors in this experiment include: not using the correct height, failure to utilize the computer programs efficiently thus skewing the time calculation. Improvements for future experiments include: getting familiar with the tools that are used in the experiment and making sure the procedure is followed through. QUESTIONS AND EXERCISES 1. It is possible to use a stopwatch to measure the ball’s falling time, however, the accuracy in the g measurements will not be as precise as the time pad. 2. There is a 95% difference between the measured value of the acceleration and the accepted value. 3...

...Research Paper Part I: Physics strives to identify fundamental principles governing the build and deportment of matter, the engenderment and movement of energy, and the interaction of matter and energy. Some physicists use those principles in theoretical areas, such as the nature of time and the beginnings of our universe, while some work in practical areas such as the development of advanced materials, optical and electrical devices, and medical equipment (BLS, para. 2). I chose physics for my career research paper because I have an intellectual curiosity for the world, the universe, and everything in between. I want to understand how matter moves through spacetime, and how the universe behaves. Understanding physics also means understanding many other scientific areas of study, thus providing an intimate knowledge for reality as we know it. Many physicists work in laboratories, where they design and perform experiments with sophisticated equipment. Some of that equipment includes lasers, particle accelerators, electron microscopes, and mass spectrometers. Although much research may be conducted through experiments in the lab, physicists still spend much time in offices planning, recording, analyzing, and reporting on research. Many who are deeply involved in research way also work very long or irregular hours. For basic research positions, independent research in industry, faculty positions, and advancement to managerial positions, a Ph.D in physics or related field is...

...Conforming our beliefs to the evidence of reality is a hard transition for most. Unraveling the deep truths about our origins in this universe is confronting the very foundations of our society’s historic religious establishments. Could modern science bring us closer to a true pantheistic god of beauty, or destroy all notions of a sense of purpose (Krauss, 2012)? Regardless of your faith, the laws of physics are proving every day that something can come from nothing. A god of the gaps is probably the most common, as well as most elementary, argument for debating science vs. religion. This idea is simply employing a divine meaning to things that science has no answer to. It is often a question of why, and assumes purpose to everything. One thing that science cannot refute is a purpose to our world. It is scientifically inert, that is to say that there is no plausible way to test its predictions. The scientific method is just field testing the observable world we see around us. We are all naturally inquisitive; we thrive to find our “purpose” in the world. But this, I believe, is simply a limit to our senses. When there are questions that science cannot answer, such as why we came to be, skeptics often say that it is outside the bounds of our universe. This, to me, is just a lazy answer. The god of the gaps is a “fill in the blank” answer to everything that has been so far, untestable. This does not mean that anybody has the right to invoke a spiritual...

...We now know that the speed of light is way too fast to be measured by this experiment. Galileo brought upon the public the basic idea of relativity, that “the laws of physics are the same in any system that is moving at a constant speed in a straight line, but not of its speed or direction.”(Hoskin, Michael A 62) While Galileo's statements of mathematics to experimental physics were new, his mathematical methods were the usual ones at the time. Even as there were many other studies he went in and different experiments there were way too many to even put in but as were listed above were the major one’s that later affected future and current people, with their views and their discoveries that effected history...

...If the universe is described by an effective local quantum field theory down to the Planck scale, then we would expect a cosmological constant of the order of . But the measured cosmological constant is smaller than this by a factor of .This discrepancy has been called "the worst theoretical prediction in the history of physics!".Some supersymmetric theories require a cosmological constant that is exactly zero, which further complicates things. This is the cosmological constant problem, the worst problem of fine-tuning in physics: there is no known natural way to derive the tiny cosmological constant used in cosmology from particle...

...Is Science the only sure path to Truth? Physics is “the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms” (Oxford Dictionaries). Till the first half of the eighteenth century, physics was a branch of natural philosophy. It “became widely used in its modern sense (i.e., excluding the life sciences, geology, and chemistry) during the second half of the eighteenth century” (Olson, 2002, p. 301). Olson (2002) explains how physics is divided into two main categories. He states that topics treated before the middle of the last decade of the nineteenth century are said to be parts of classical physics. On the other hand a group of topics that emerged after about 1895 is said to make up modern physics. Since physics is a broad area, in this essay, I specifically focus on one topic from modern physics, namely quantum physics. I will evaluate whether quantum physics can lead us to ‘Truth’. In this paper, ‘Truth’ refers to quantum events. First, I will portray how quantum events are filled with uncertainties; I will then list three answers given by physicists to explain why uncertainties are present. I will then move on to show how quantum physics offers conceptual parallels to ideas in religion. I will mainly discuss the role of holism character in quantum systems. Finally I will evaluate whether god is the reason...

... astronomer, and philosopher who played a major role in the scientific revolution. Galileo has been called the "father of modern physics Galileo's theoretical and experimental work on the motions of bodies, along with the largely independent work of Kepler and René Descartes, was a precursor of the classical mechanics developed by Sir Isaac Newton. Galileo conducted several experiments with pendulums. It is popularly believed that these began by watching the swings of the bronze chandelier in the cathedral of Pisa, using his pulse as a timer. Later experiments are described in his Two New Sciences. Galileo claimed that a simple pendulum is isochronous, i.e. that its swings always take the same amount of time, independently of the amplitude. In fact, this is only approximately true. Galileo also found that the square of the period varies directly with the length of the pendulum. It is said that at the age of 19, in the cathedral of Pisa, he timed the oscillations of a swinging lamp by means of his pulse beats and found the time for each swing to be the same, no matter what the amplitude of the oscillation, thus discovering the isochronal nature of the pendulum, which he verified by experiment. Galileo soon became known through his invention of a hydrostatic balance and his treatise on the center of gravity of solid bodies. While a professor he initiated his experiments concerning the laws of bodies in motion. After suffering fever and heart palpitations, he died on 8 January...

...Chemist and physicist Ernest Rutherford was born August 30, 1871. Ernest, a pioneer of nuclear physics and the first to split the atom was awarded the 1908 Nobel Prize in Chemistry for his theory of atomic structure. He was named “Father of the Nuclear Age.” Ernest Rutherford was very intelligent and responsible for remarkable discoveries. Ernest Rutherford was born on August 30,1871 at Spring Grove in rural Nelson. He was the fourth of twelve children in his family; James and Martha were his parents. Martha believed that knowledge was power, and placed a strong emphasis on her children’s education. He grew up helping on the farm after school. Ernest’s parents and teachers had a major impact on his life. Mr. Ladley, one of Ernest’s teachers,...

...The University of Copenhagen is where Niels Bohr went to school following his passion in physics. Bohr would go on to do great things with the help and influence of his father and his father's best friend Professor Hoffding, to steer the way for him to become the person he visualized and set to be. To begin with, Bohr a very educated and sought after education to always learn, was introduced to epistemology, the theory of knowledge that justifies the differences from others opinions, capturing a thought to learn right from wrong. He learned philosophy and became a part of him to discover things himself which he would later on do. Bohr and a classmate name Harald were a part of a class with Professor Hoffding, as they debated philosophy,...

...eventually were found out to be planets moving around the sun (although at the time they were discovered, it was thought that everything revolved around the earth); albeit all of these stars and planets were discovered before Galileo’s telescope. The tool still helped gain better calculations of the stars, which helped Galileo support Nicolaus Copernicus’ heliocentric (sun-centered) solar system as opposed to the geocentric (earth-centered) solar system that people in those times believed. With Isaac Newton, one of the most famous physicists, discovering most of laws of motion through his studies in astronomy, Philosophiae Naturalis Principia Mathematica, one of the greatest works in the Scientific Revolution, was born. From Newtonian physics, theories of fluid mechanics, electricity and magnetism, and most importantly, quantum mechanics. Further along the line of the history of telescopes, humans eventually needed to see deeper into space. This was revolutionary because now mankind wasn’t just looking up into the constellations and the movement of the sun and the moon, now they were actually...

...feel is a little misguided, or a dead end. In most instances, this view is correct but, every so often, a scientist has a revelation. More often than not, they feel the weight of scientific and public opinion, and become ridiculed. However, slowly but surely, other scientists try out the research, and a few lost voices in the wilderness increase into a new way of thinking. For example, explorations of chaos theory took a long time to take root, and his ideas were marginalized, because they lay outside the established classical paradigm of physics. Early Chaos Theorists found difficulties in receiving funding, finding supervisors, and finding journals willing to publish their research. Kuhn’s paradigm definition is a little more than a theory, although the terms are often used interchangeably. It is a complete and overall view of a phenomenon, often relying upon some basic principles. This process continues for a long time, until some experiments begin uncovering errors. A certain amount of error is accepted, and it can be absorbed by slight changes in the paradigm. However, eventually, the basic and fundamental principles may be shown to have error and there is a paradigm shift, a way of looking at the same information in a completely different way. Probably the...
