Acceleration Due to Gravity

...Acceleration Due to Gravity Introduction In this lab you will measure the acceleration due to gravity near the earth’s surface with two experiments: first, by determining the time for a steel ball to fall a known vertical distance (free fall), and then second, by measuring the velocity of a cart at various points as it glides down a slightly inclined and nearly frictionless air track (slow fall). Equipment Part 1: Free-Fall • Free-fall apparatus (steel plate, drop mechanism) • Electronic Timer • Steel Ball Part 2: Slow-Fall • Air Track • Electronic Timer (may be different brand/model than in Part 1) • Gliding Car • Laser Photogate Background: Free Fall Acceleration Under the constant acceleration of gravity near the Earth’s surface, g, the vertical position, y, of a falling object is related to the time it has fallen by 1 y = y 0 + v 0 t " gt 2 2 where y0 and v0 are the initial position and velocity, respectively. The distance fallen after a time, t, has elapsed is: ! 1 y 0 " y = gt 2 " v 0 t 2 If you release the object from rest, v0 = 0, the equation simplifies to ! y0 " y = 1 2 gt 2 By varying the distance the ball drops and measuring the corresponding transit times, we can determine the acceleration of gravity from a best fit line to a linear graph of the experimental data. ! ! Procedure: Free-Fall Acceleration A diagram of the experimental apparatus is shown in Figure 1. When the ball loses contact with the release mechanism, the timer starts counting. It......

Geometric Gravity

...Geometric Gravity George Gabriel Geometric Gravity Science, the never ending pursuit of answers, it has solved many questions thought unsolvable. It has made the impossible possible time and time again. Yet one question has stood the test of time and to this day remains unanswered. How to unite gravity with the unified field theory or UFT. But to answer that question other questions must first be asked such as, what makes gravity? Scientifically what makes gravity is unknown, gravity is just this mysterious force that exerts itself on universal and atomic scales. We understand what it does but we don’t understand what makes it happen. Throughout my studies I have come across a consistent that I believe needs to be examined and that is, not only a correlation between the geometric patterns found in multi-year planetary orbits and those found when studying Cymatics but also the correlation of those to the orbital patterns of electrons around their nucleus on the atomic level. You may be asking yourself what exactly is Cymatics, or even perhaps what is this lunatic talking about? To begin to answer these questions I will describe Cymatics first. Cymatics is the study of visible sound and vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. Different patterns emerge in the exitatory medium depending......

Specific Gravity & Absorption

... Malinao SPECIFIC GRAVITY AND ABSORPTION I. OBJECTIVE To determine the Apparent, Bulk (Dry), Bulk (SSD) specific gravity and the absorption in percentage of the coarse and fine aggregate sample II. PROCEDURE WITH PICTURES COARSE AGGREGATES 1. Approximately five kilograms of the coarse aggregate sample was taken by method of quartering. The 5 kg coarse aggregate sample was sieved by the 3/8” sieve and the materials passing through were discarded. (Figure 1) 2. The sample coarse aggregate was washed thoroughly with water to remove dust and other materials coating the individual aggregate and the sample was soaked under water for 24 hours. (Figure 2) 3. The soaked aggregates were removed and each aggregate was wiped to saturated surface dry (SSD) condition. (Figure 3) 4. The SSD weight in air (B) of aggregate to the nearest 0.1 gram was obtained. This was done quickly to prevent evaporation. 5. The weight of the wire mesh basket was determined. The coarse aggregate sample was placed in the wire mesh basket and its weight in water (C) was determined. The weight of the wire mesh basket in water was subtracted. (Figure 4) 6. The wet aggregate was placed inside the oven at a temperature not exceeding 110°C and the constant oven dry weight (A) was determined. (Figure 5) 7. From the data obtained, the specific gravity and absorption as defined below were solved: a) Apparent Specific Gravity = AA-C b) Bulk Specific Gravity (Dry) = AB-C ......

Paper and Gravity Waves

...gravitational waves will occur within the next decade. 2 The Detection of Gravitational Waves, How Close Are We? Einstein's general theory of relativity was published in 1915.1 Since that time many of the predictions derived from the theory have been experimentally observed. Three main examples are the bending of light by gravity, the red-shift of light traveling in a gravitational field, and the precession of Mercury. Einstein's theory has been credibly established because of observations like these. There are still other predictions that have yet to be observed. The detection of gravitational waves is one of these predictions. It was discovered in 1916 that the general theory of relativity predicts the existence of gravitational waves. “Gravitational waves are perturbations in the curvature of spacetime propagating with the velocity of light. They are caused by accelerating masses.”2 In order to understand the concept of a gravitational wave it is helpful to understand gravity as explained by the general theory of relativity. Relativity does not analyze gravity in terms of forces and acceleration as in Newtonian physics. Instead it explains gravity in terms of the geometry of spacetime. Space time is a very difficult concept to visualize. It is made up of the three positionaxes, x, y and z, but also includes the dimension of time. It is the fourth axis of time that makes spacetime difficult to conceptualize. Spacetime is all around us. It maybe helpful to think of it......

Wide Application Fields of Gravity Destoner Machine

...Gravity destoner machine is not only widely applied for removing stone from all kinds of seeds and grains, also can be used in other fields such as remove stone from active carbon. Using the difference of specific gravity and suspending speed between grains and stones, and by means of air stream passing up through space of grain kernels, the stoner separates stones from grains. GRAVITY DESTONER MACHINE produced by Win Tone Machinery is absolutely reliable. The heavy impurities such as stones having the same size and shame with grain kernels are in the lower layer and move to the stone outlet by means of directional, slope and reciprocating movement of stoning sieve plate, while grains floating in the upper layer roll under self gravity to discharge outlet, so as to separate from grains the stones having the same size and shame with grain kernels. Wintone Machinery is mainly engaged in gravity destoner machine, wheat processing engineering, wheat equipment manufacturing, installation, commissioning and training service.

Center of Gravity Analysis – an Actual or Perceived Problem?

...Andersson ChP 07/09 Tutors Kersti Larsdotter Truls Gustavsen Center of Gravity Analysis – an Actual or Perceived Problem? Abstract Centers of Gravity (CoGs) analyses deliver vital input to the operational design. However, there are a great number of theories regarding the phenomenon which can create a certain degree of confusion. The diversity in theories may lead to misdirected mental energy where the focus is to discuss theories instead of using the theories at hand efficiently. The question is if the diversity in theory is an actual problem or if it just perceived as such? This research identifies the similarities and differences in the theories of Milan Vego and Joseph Strange & Richard Iron regarding CoGs, their sub elements and methods for analysis. The impact of the differences on the practical result is then surveyed by implementing the theories on adelimitated phase of the Falklands War, in order to conclude if the differences have a decisive impact on the product of the CoG analysis. The result of this thesis indicates that the diversity in theory is a perceived problem. The identified divergence does not reflect crucially on the CoG analysis and the variation of the input provided to the operational design is minor. The CoGs and the critical vulnerabilities identified are the same or at least similar, no matter which of the two theories was used in this research. Key words: Centers of Gravity, Military Theory, Operational Art, Operational Design, Milan......

Gravity Model at Gcc

...Journal of Economic Integration 23(1), March 2008; 42-56 The Trade Potential of the Arab Gulf Cooperation Countries (GCC): A Gravity Model Approach Dr. Houcine Boughanmi Sultan Qaboos University Abstract The GCC region has recently witnessed the creation of a customs union between the countries of the region as well as the signature of many free trade areas with countries/blocs outside the region (i.e. US and EU). The purpose of this paper is to investigate the potential of trade of the GCC countries within the context of the old and the emerging preference trade arrangements in the region of Middle East and North African Countries (MENA). A gravity trade model was estimated based on pooled time series-cross-sectional data of bilateral trade of the MENA countries with their major trading partners. The results indicate that in spite of the fact that the share of GCC intra-trade is too small in absolute terms, it is actually higher than expected on the basis of underlying trade determinants. However the level of the GCC intra-trade has not changed significantly over the years and had probably reached its full potential during the first decade of the GCC creation. Trade with the Mashreq countries are more than expected, while it is less than expected with the Maghreb countries despite the implementation of the GAFTA a decade ago. The GCC trade with the European Union and the US was found to be quite intensive although no formal trade arrangement existed between the GCC and......

Specific Gravity of Propylenely

...voluntarily to be deported to what the Germans styled “labor camps” to the east.2 Unfortunately for them, most of these people found themselves in a gas chamber instead of a workshop. People in the ghetto heard rumors of mass extermination but did 2 not believe those rumors could be true; after all, this was the twentieth century. Their thirst for life was so great that they resisted the demands of younger, more militant Jews and refused to use what aid money filtered in to buy weapons. The Joint Jewish Organization appealed to the world outside of Poland for help, and millions of dollars poured into the country through back-channels. However, much of this money was funneled into the hands of the Polish Home Army because it was actually fighting a guerrilla war against the Nazis and had access to outside sources of money. Jews inside the ghetto had to rely on whatever source was available to serve as a conduit for the funds; sometimes the conduit simply kept the money for some other purpose.3 In the face of Nazi determination to eliminate the ghetto altogether, the uprising began shortly before Easter in 1943 when various groups inside the walls resisted the Germans with whatever weapons came to hand. They had numerous homemade weapons that were forerunners of the improvised explosive devices seen in later conflicts. Their arsenal included Molotov cocktails, exploding mines filled with nails and screws, rifles, handguns, and what observers described as......

Gravity: an Analysis of Madness in Wieland

...Jared Cruz Professor Estrada American Lit. 1 April 18th, 2015 Word Count: 1,799 Gravity: An Analysis of Insanity in Wieland To some, the definition of madness is a state in which one is mentally unstable and filled with irrationality. To others like famous scientist Albert Einstein, true insanity is doing the same thing over and over expecting different results every time. Regardless of how it is defined, one fact about insanity or madness remains true to this day and can be summed up by one quote from perhaps the most famous insane character of all time, the Joker: “Madness, as you know, is like gravity... All it takes is a little push!” This very idea of insanity and how susceptible to madness the mind can be is a central theme throughout Charles Brockden Brown's Wieland. In the novel, one of the primary forces behind everyone's growing paranoia and dementia are a series of voices that literally cause the protagonist's brother, Theodore Wieland, to murder his wife and children. Of course the voices not only affect Theodore, but rather the entire community as a whole, namely the protagonist herself. Clara Wieland is just as easily prone to the insanity that overcomes her circle of friends and family. Many times throughout the novel, Clara demonstrates various qualities of irrationality, such as contemplating suicide and struggling to maintain grasp onto reality. While these are prime examples of madness within the novel, one's sanity that often goes unchecked is that...

Gravity Research Project

...Lucius Gardner Mrs. Henry AP Physics 16 February 2016 Gravity Research Project Over the past several hundred years there have been many great scientists that have come up with significant ideas and theories in the scientific field of gravitational research. These scientists include but are not limited to Aristotle, Galileo, Kepler, Newton and Einstein! Each one of these scientist have come along after another, using each other’s ideas to further expand the human species’ knowledge on gravity and how it works. They have each left a unique mark on the scientific community. The Greek philosopher Aristotle was the first of his kind, coming up with the first theory about gravity even existing around the 4th century BC. Aristotle’s belief was that there is no effect or motion in the universe without a cause for it. He believed that heavy bodies moved downward toward the center of our universe, while light bodies moved toward the Moon. A heavy body would be something like the element of earth, not the Earth. While a light body would be something like the element of fire. Aristotle also believed that objects of different weights fall at different speeds. This gave the belief that heavier objects should fall at faster speeds than lighter objects. The next scientist to have a voice on the theory of gravity is the Italian scientist Galileo Galilei. Galileo showed that Aristotle’s assumption that the speed of falling bodies is determined by their weight is outright wrong. He......

Physics Paper Gravity and Electromagnetism

...Daisy Dai Grade11 Class1 Physics Whether the Gravity is the product of the Electromagnetism I.          Introduction Gravity and electromagnetism are both the fundamental forces in the world; they are unique in physics and thought of some connections between them by some scientists. However, according to the studies, gravity isn’t a product of electromagnetism because they are juxtaposed to each other in physics’ identifications. From the formula (G=mg) created by Newton, the gravity is related only to mass. And this leads concept of gravitational fields. But the electromagnetic force are definitely different from that one. It is related not to mass but to the electric charge(F=qvB), and this leads to the concept of electric field. Since the Earth exists the gravitational field, the electric field and the magnetic field which don’t have any affiliation with each other by observing the formulas, they will not have connection with each other. But for electric and magnetic force, the sources of magnetic fields are electrical currents, caused by moving electric charges or small dipoles associated with molecular and atomic structure. So, there is electromagnetic force that electromagnetism exists in the universe. However, these forces actually have connections with each other instead of non-connection relationship. In fact, gravity is not the subordinate relationship with electromagnetism but the similar ones. All......
