Inertia and the Laws of Motion

Inertia and the Laws of Motion Inertia is the name for the tendency of an object in motion to remain in motion, or an object at rest to remain at rest  unless acted upon by a force. This concept was quantified in Newtons First Law of Motion. The word inertia came from the Latin word iners, which means idle or lazy and was first used by Johannes Kepler. Inertia and Mass Inertia is a quality of all objects made of matter that possess mass. They keep doing what they are doing until a force changes their speed or direction. A ball sitting still on a table wont start rolling around unless something pushes on it, be it your hand, a gust of air, or vibrations from the surface of the table. If you tossed a ball in the frictionless vacuum of space, it would travel on at the same speed and direction forever unless acted on by gravity or another force such as a collision. Volker Mà ¶hrke / Getty Images Mass is a measure of inertia. Objects of higher mass resist changes in motion more than objects of lower mass. A more massive ball, such as one made of lead, will take more of a push to start it rolling. A styrofoam ball of the same size but low mass may be set in motion by a puff of air. Theories of Motion From Aristotle to Galileo In everyday life, we see rolling balls come to rest. But they do so because they are acted on by force of gravity and from the effects of friction and air resistance. Because that is what we observe, for many centuries Western thought followed the theory of Aristotle, who said that moving objects would eventually come to rest and needed continued force to keep them in motion. In the seventeenth century, Galileo experimented with rolling balls on inclined planes. He discovered that as friction was reduced, balls rolled down an inclined plane attained almost the same height rolling back up an opposing plane. He reasoned that if there were no friction, they would roll down an incline and then keep rolling on a horizontal surface forever. It wasnt something innate in the ball that caused it to stop rolling; it was contact with the surface. Newtons First Law of Motion and Inertia Isaac Newton developed the principles shown in Galileos observations into his first law of motion. It takes a force to stop the ball from continuing to roll once it is set in motion. It takes a force to change its speed and direction. It doesnt need a force to continue moving at the same speed in the same direction. The first law of motion is often referred to as the law of inertia. This law applies to an inertial reference frame. Corollary 5 of Newtons Principia says: The motions of bodies included in a given space are the same among themselves, whether that space is at rest or moves uniformly forwards in a straight line without circular motion. In this way, if you drop a ball on a moving train that is not accelerating, you will see the ball fall straight downward, as you would on a train that was not moving.

What are the similarities and differences in the operations management Essay

What are the similarities and differences in the operations management of bmibaby and in the case of Fuller, Smith & Turner PLC (Brewery) - Essay Example It was founded in 1845 in Chiswick as the Griffins brewery. The logo for the Fuller, Smith and Turners brewery states that quality, service and pride are provided in equal measures by them. The main product of the company is beer and it also operates pubs. The geographical area that Fuller, Smith and Turner and Bmibaby cater to is the same. Both of them are located in England but there is a huge difference in the market they cater to. There is a huge difference in the history and background of both companies. The brewery is well known because of its ancient roots and traditional methods whereas Bmibaby is a company which hasn’t even completed a decade of existence. Smith, Fuller and Turner currently own 363 pubs and supply their products to them. The range of products is very wide and includes Chiswick Bitter, London pride and ESB. A major factor of their success is the companys recent acquisition of the Gale group which added another 111 pubs to its empire. This move ensured the elimination of a major competitor from the scene. Besides that Smith, Fuller and Turner are well known because of the quality of their products. The Chiswick Bitter has been known as the Champion beer of Britain and the record has been unmatched. The brewery also operated by adding more and newer beers to its portfolio thereby reducing monotony of products. Michael Turner, the CEO of the company once said that We have a long-term strategy, strong balance sheet, excellent cash flow generation and an experienced management team and are well placed to meet the challenges ahead. (Review) In contrast Bmibaby works by providing its services at the lowest cost possible. They provide services which are already there in the market but its core competency lies in the fact that it custom provides those, thus charging the customer for what it wants. As compared to the brewerys 363 locations, it operates from four

Public Relations (event management) Essay Example | Topics and Well Written Essays - 1000 words

Public Relations (event management) - Essay Example This plan outlines the pre-launch activities to be carried out in order to create publicity and awareness for the launch. It will highlight the approaches to different marketing and promotion styles that will prove essential for the publicity. The event management team has conducted meetings with the hotel officials and planned a brief for the mega event to be held on 30th March 2011. How to approach the local media? Advertising through the media can be quite expensive. In order to lower the costs, a partnership with a media channel to advertise is recommended. Since opening a 5 star hotel is a large event, the national newspaper will be a good choice. The advertisement activities are to be done prior to the event. A brand campaign at the right time will be required to make the event known to the masses. There will be some gap between the event and the advertisement, so that people are ready and aware of the activities. This might also help to generate some kind of sponsorship theref ore it is suggested to advertise 2 weeks before the event. Other than that, exclusive invitations could be sent out in some of the wealthy residential areas that are home to the upper class of the city (Damster, et al 2006) Since a five star hotel can cater to many people, flyers or posters are to be put in some of the posh places to advertise the event. Inviting public figures to a hotel opening can be a great way of gaining media coverage. The press would definitely want to cover the event if celebrities are attending it. Sponsorship through television channels will allow the event to reach more targets than sponsoring through some product or service brand. In this way television coverage will be available on the day of the event and will be a major attraction for the attendees. Having sponsors is a great way of gaining media coverage. A press release The press release is to be made exclusively for the event. It will send out the message well and frequently. It is to be made sure that the press release is exciting and can appeal to the audience and not give them a chance to overlook the content and the event. So it should be worded very strongly (Damster et al 2006). For attracting target audience the press release will have a catchy headline in bold letters formatted in the middle. A subheading will be provided underneath to summarise event media release in a line with a smaller font than the main heading. For journalists to get an idea, all main points will be incorporated in the first two paragraphs. All the 5 Ws i.e. â€Å"who, what, when, why, and how† will be briefly stated. A quote from the spokesperson will explain the significance of this event. At the bottom, contact details will be provided for people to get in touch. In publishing the press release, a give out kit will also be an attractive way to gain publicity. This kit will be in the form of a folder containing photos of the hotel, details about the owners and other details about the op erations such as descriptions of facilities, events and rates. The press release is to be brief, while giving out enough information to keep the audience interested and curious (Fier, 1993). Media briefing presentation for the event

Unhappy Customers Personal Statement Example | Topics and Well Written Essays - 750 words

Unhappy Customers - Personal Statement Example Unhappy customers On the other hand a satisfied customer pulls number of other customers towards the organization and service. Customers help defining success in a way that they set benchmarks for what is in demand, and things that need to be avoided or are out of date. For them its more about quality than the costs, they are willing to pay more for comfort and quality rather than low quality and more hassle of repair and low productivity. The policies so made should be customer centric. Customers’ response is related to the online sales and services as well as the physical world businesses responses. A relationship matrix can be defined in this way to identify all the factors and benefits that may be achieved through successful implementation of customer response and satisfaction. A prime example in this regard was seen when a musician had his guitar damaged in an aero plane flight and when the compensation was demanded, it was not provided; the same musician went on to make a song on the Unit ed Airlines services and this incident and ended up with millions of views to his video and song, this earned the company a bad name, and in the end they had to apologize and provide compensation, all to customer dissatisfaction (Cheryl Hamilton 2010). Customer Relationship Management is an approach towards establishing a relationship with the customers and working to their satisfaction and demand, in other words, a key to success. C.R.M stresses upon focusing on individual customer rather than masses, this helps knowing the customer behavior, the past experiences. The entire process would focus on the manufacturing strategy, the services to be provided after the product is prepared. Customer identification, differentiation, and personalization are few important terms and phenomena that need to be taken into consideration while dealing with the customers since every customer has a different taste than other, and so is the demand and requirement. The differentiation aspect helps identifying the customers that are more regular, have larger stakes on hold, and are slightly sensitive to the subject and services, and since all resources might not be available every time, implementing them at the right place and towards the right custome r becomes important. Paretho Principle is another similar concept related to the customer response. It is also known as the 80-20 rule, and according to it, the 20 percent customers that makes up for 80 percent of the sales. It is being stated that cost of making a new customer is far higher than retaining one. Even the 5 percent customers retained, results in 25 percent increase in overall productivity of an organization (Ronald S.Swift 2001). Besides customer satisfaction the individual characteristic of the product or service defines the rate of customer turnover from any company or brand. Customer response is considered a Key performance Indicator (K.P.I) and based on its value; the company’s performance is measured in the marketing world. Surveys are being conducted about particular product or service, or the overall experience of the customers with the company, based on their response in the rating scale, further strategies are being devised that helps molding the struc ture of company according to the need of customers. A company must be open to claims, and repairs, however the best policy is to prevent rather than repair, it helps in many ways, not

Knowledge and Its Affect on the Society and Its Spontaneous Essay

Knowledge and Its Affect on the Society and Its Spontaneous - Essay Example To answer this Althusser (1978) coined the term â€Å"Ideological State Apparatuses† and â€Å"Repressive State Apparatuses†, gives that necessary epistemological break, more analytically than Gramsci (1971), in his theory of social â€Å"hegemony†. In contrast to Bourdieu's concept of habitus, the Ideological State Apparatuses consist of social institutions like school, university etc that help spread a particular discourse of thought-process and archetypal pattern of understanding in a particular way (like Christian concept of good and evil). The Repressive State Apparatus are agents of repression, like the Police, that teach by force and thus maintain the necessary consensus. While the institutions teach through the medium of language that is itself coloured with discursive power to subjugate a subject in the given hegemony almost without any conflict or force. Lacan (1968) explains this linguistic paradox in his theory of language where he says that the stage when s subject enters the realm of the â€Å"symbolic† sphere, the self/consciousness becomes a complex site where one loses the capability to express beyond that given medium of language, which is finite and a complex site of power play. Language is not neutral, but an agent of defining this ideological and hegemonic base. Quite pessimistically, the answer has been given as no. Since the state is a billion-eyed monster keeping a watch on its subject (imagine Orwell’s 1984), the state apparatuses reach out adventitiously even to the furthest grass-root level and teach by force or by apparently ‘neutral’ force to form subjects who cannot escape this ‘interpellation’ (Althusser).

Study on the Internet Assignment Example | Topics and Well Written Essays - 750 words

Study on the Internet - Assignment Example PhD is most likely a level that a researcher must examine any subject of choice in details, for a number of years in his or her course. In this sense, it was decided to study the matter of sample size in PhD studies’ context. The two major concerns of this study were to find out the number of participants who make use of qualitative interviews in their PhD studies, and if this numbers differ depending on the procedural approach. The method of the study A PhD database content analysis was carried out on the â€Å"Index To Theses: A comprehensive listing of theses with abstracts accepted for higher degrees by universities in Great Britain and Ireland since 1716†. This research was performed between the third of August, and twenty forth of August, 2009 (Mason, 2010). In the collection, 532,646 abstracts were used to discover PhD studies, indicating that they had utilized qualitative interviews to collect information. To find out any dissimilarity between diverse research t echniques, a classification of 26 varying qualitative research techniques from different disciplines were used. The methodological traditions were classified into four groups, namely: discovery of regularities, reflection, language characteristics, and comprehension of action or text meaning (Gravetter & Forzano, 2011). The researchers used a â€Å"standard search† with a number of parameters applied: if â€Å"any field† entailed â€Å"insert methodology†; if â€Å"any field† entailed interviews†; and if â€Å"Degrees† entailed PhD. The study looked solely at the use of individual to individual personal interviewing, meaning that focus groups were excluded from this analysis. The outstanding studies were collected using samples. A search on the abstracts was carried out and the following details were recorded on each: category of qualitative research; the methods used; and the number of interviewees who participated (Mason, 2010). Findings Th e findings by the authors indicated that in general, the range of the participant numbers used was between 95 and 1. Of the 560 studies examined, the mean and median were 31 and 28 respectively, perhaps suggesting that the central dispersion measures were consistent in general. It was clear that some approaches used interviews in their methodologies than others. Out of the 26 qualitative methods, 9 returned over 10 studies. The most popular techniques utilized in PhD studies as per this analysis were: life history, grounded theory method, discourse analysis, case study, phenomenology, content analysis, hermeneutics, action research, and symbolic interactionism. Case study projects were the most frequently utilized interviews; 1,401, while the grounded theory accounted for 429, with an inclusion criteria of 41%. On the other hand, qualitative evaluation accounted for the highest mean in the number of participants at 42, while ethnography communication recorded the lowest at 34. Discu ssion The most popular sample sizes were 30 and 20. Forty, ten, and twenty five followed the sequence. The considerable high proportion of studies using the multiples of ten to act as their sample stands out as the most vital finding of this analysis (Rubin & Babbie, 2009). There is no hypothesis-driven or logical reason why samples that end with any single integer would prevail than another in qualitative PhD researches that uses interviews. If the directing concept for qualitative resea
