Energy Conservation - Lab Report Example The gravitational potential energy of an object refers to the energy an object possesses due to its location relative to a reference point. Considering an object close the Earth’s surface the gravitational potential energy is given as (Cutnell et al. 18) Where g is the gravitational acceleration, m is the mass if the object and y are the vertical position of the object relative to an arbitrary reference point. The following graphical plot illustrates the variation of kinetic and potential energy of the oscillating systems studied in this lab For a swinging pendulum (oscillatory system) there is the constant conversion of energy to kinetic energy, potential energy and back to kinetic energy however the total energy at any given time is always a constant. The energy stored in compressed springs or elastic objects is another form of potential energy that is mathematically given as (Cutnell et al. 25). Notably, when there is no energy input into the system, the total mechanical energy will remain constant. The linear plot shown in the printout shows the constancy of mechanical energy with time defined by same slope over given time. Using the K/m and y values shown in the table of results above the following graphical plot was obtained that shows the relationship between the K/m and the vertical displacement Using the Excel graphical plot above the gravitational acceleration was evaluate because for an oscillating system like a pendulum maximum potential energy (maximum displacement) is experienced when the kinetic energy is at a minimum. Equally maximum kinetic energy for a simple pendulum corresponds to the point where there is minimum vertical displacement. At the point where K/m is equal to zero, the potential energy of the system is at a maximum this corresponds to the point where the value of the arbitrary displacement is 0.1089. The potential energy per unit mass at this point

People Resourcing - Essay Example The year 2008 saw the economic market hit a bump in a rather smooth road that it was enjoying over the last decade. The year saw the emergence of the global financial crisis that hit the job market all over the world and it has seemed difficult for the market to regain its stable shape. Banks have increased their lending rates over time making it rather difficult for entrepreneurs and other businesses to borrow money from them and consequently expansion of businesses has reduced drastically. This is important information for companies that may seek to continue with traditional trends of haphazard recruitment (McKenna & Beech, 2002, 234). With the minimal number of expansions made by companies, it has become rather difficult for more employment opportunities to pop up in these businesses, which has been a major factor to observe when considering people resourcing. This is from this that companies have faced challenges in that every business seeks to offer more employment opportunities in an effort to improve the quality of its brand or reach a greater market (Roberts, 2000, 164). However, the money required to pay the new employees has become hard to make and thus it is important for employers to reduce the recruitment rates for their companies in an effort to cope with the current market trends. Human Resourcing is very important to a company in different ways. One other manner through which it helps a company is in terms of assisting the organization in achieving both contemporary and future business needs. Human Resourcing incorporates the aspect of having employees carry out different activities in an effort to achieve the various goals that a company sets. One of the major needs that a company has both short term and long term is the attainment of a large profit margin. This is important for the company to bear the ability to maintain existing business assets and in an effort to obtain others for the eventual growth of the company. Businesses should underst and that this is attained by having personnel specialized in various fields that makes it easier for the management of the company to coordinate the activities of each person (Bloisi, 2007, 43). Human Resourcing is also important in that with a large number of personnel and the business products reaching out a great number of people, there are increased chances of investor opportunities in the business. In the contemporary environment and with the existing tough market, investors have started decreasing the amount of investments they make on companies that do not offer the required results. However, an increase in personnel and a larger network of workers ensures that not only the business provides quality products for the customers, but also that the products reach out to a larger community. A combination of both the quality and a large network of workers brings in new investors interested in the company and subsequently growth of the company is assured (Beardwell, Holden & Claydon , 2010, 127). Manufacturing jobs have had the greatest impact on the economy of many different countries. However, contemporary market trends have revealed that the service sector has began making more profits as
