Roller Coaster Physics :: physics amusement theme park

Undoubtedly roller coasters are the kings of amusements parks. Whether you enjoy a older, rickety wooden roller coaster with its thrill of positive and negative G's and a fairly wobbly feeling. Or, you prepher something newer, a tube steel roller coaster. A coaster that is faster, one that includes death defying speeds, hairpin turns, and of course the crï ¿ ½me de la crï ¿ ½me, loop de loops. However, regardless of you personal tastes and preferences, through exploring this page you will find that all roller coasters are indeed bound by the same fundamental laws. Laws that govern everything in our daily lives, the laws of physics. While exploring this paper, please remember this simple fact: Roller coasters are fast, they're fun, they're exciting, but above all, they're PHYSICS! The basic physics that apply to roller coasters can be seen when we examine some of the simple thrills of roller coasters: * The relation between Height and speed * Positive and Negative G's * The corkscrew * The loop de loop Some of you out there might be wondering, what exactly I mean that when I say that there is energy associated with roller coasters? And the answer is very simple, although roller coasters don't produce, or use energy as most people today would define it--electricity. They do posses what physicists call kinetic (or mechanical) energy, which is the energy of motion and is defined with the equation: K= ½mv ² which is read: ï ¿ ½Kinetic Energy equals one-half mass times velocity squared.ï ¿ ½ However, there is another type of energy associated with roller coasters, and that is gravitational potential energy, which is simply the energy that the roller coaster has due to its position above the earth, and has the formula: U=mgh which is read: "Potential Energy equals mass times velocity times height." Then, when we take into account the First law of thermodynamics (also called the conservation law), seen below: The First Law Of Thermodynamics: ï ¿ ½Energy can be changed from one form to another, but it can not be created or destroyed.ï ¿ ½ click here to see the source page. So, after taking thermodynamics into account we see that at any given point during the roller coasters ride, (granted we are using a traditional roller coaster in which there are no extra chains, or engines to lift it other than the first hill, and that friction is negligible) we see that:

ID System

As computer technology changes in such a fast phase, many business firms and institutions try to cope up by upgrading computer system constantly in order to stay competitive. There is no doubt that computer is a must asset in all professions, because it offers more efficient way to process transactions. There are still institutions that use manual processing on their transactions and their system are not yet improved. Through this, it is inevitable to commit errors, troubles and it is time consuming.Access Computer College is a private school and has seven branches that are located in Metro Manila. It was established in 1981 and owned by Mr. Romeo T. Karate. Students, professors and staffs of these schools particularly in Cabaret branch are just using an ordinary ID card in entering and exiting the school campus. As long as an ID is worn, it is valid for the entry that is why outsiders are hardly identified. The school doesn’t have an organized and secure ID system that can ma ke everyone’s life easy and convenient to avoid the occurrence of problems in their transactions.So the proponents decided to propose an ID system with SMS notification and ID scanner to provide a better way of dealing with transactions like information and security purposes. This study is descriptive  and explanatory research endeavor. It seeks to inform the reader about the benefits and advantages of having more convenient and systematic ID system because indeed, high technology and security is related to each other.Having convenience in all task performed in daily living is very helpful using high technology equipment. The proponents will introduce a type of security system that will help a lot in terms of identifying and verifying students, faculties and staffs using the barcode scanner. Student’s ID card is a gate pass with a network-based system that will monitor the time in and out of the student inside the campus and directly send information to their parents /guardian. This system is about security and information that is stored in a database needed for future references.Conceptual framework Conceptual Framework is the clarification of all the activities and process of the entire ID system. This study used the System Development Life Process define as a logical process used by a system analyst to develop an information system, including requirements, validation, training, and user. The SDLP is originated by Elliott & Strachan & Radford (2004), The System Development LifeProcess used by the proponents to show the process of the entire development of the system.Figure 1.1 System Development Life Process of Access Computer CollegeThe importance of this study is to develop an ID system for Access Computer College. In the stage of Identifying the Problem, the proponents gathered information about the particular problem encountered by students and staffs of the school.In the stage of Planning, the proponents carefully analyzed the possible ex planation that will help to solve the identified problem of school in their current system. The proponents made some interviews on some students and staff about the problems they encountered.In the next process which is the designing, the proponents visualize or conceptualize a good interface that is suitable for the institution’s name and profile. In the stage of system development the proponents began to code using the Microsoft Visual Basic 2010 as programming language and Microsoft Access Key as Database.In the situation of system testing, the proponents try the system to identify some errors or inconsistency of it and if there are some inconsistencies, the proponents will debug or code the system. The proponents conducted the intensive testing program and updating to prevent errors and viruses and to assure that the system will not cause any malfunctions and inconsistency. Next stage is system evaluation, the proponents gathered feedbacks and comments from the user of th e system. The next is the system implementation where in the proponents will implement the system to the said school. The last stage is the system maintenance. The system will be under a warranty services, the warranty covers system consultation, system tutorials, system check up and debugging for possible and encountered errors. System enhancement will not be covered by the system warranty.Statement of the Problem The ID system study is created for the security and information for Access Computer College, Zabarte Branch. The study sought to answer the following questions: 1. What are the common situations usually encountered in using the current system of Access Computer College? 2. How can this ID system improve the security and information of students and staff of the school? 3. Is there any significant difference between existing system and the proposed system in terms of:Accuracy Accessibility Efficiency Security SpeedScope and Limitation This part tells the capability and limi tation of the program which the proponent will need to develop. Scope Log in modules can be used by Admin and/or authorized personnel. Searching files/records of students, professors and staffs are in order. Adding files/records will be done by a designated person only. Saving of files and records can be done according to the information. Only the Admin has the authorization to add, change, and delete the students’, professors’ and his/her accounts. The two command buttons; edit button and delete button will be enabled if the verification code is right. The system is using USB Modem as its gateway for sending mesagesLimitationLog in modules cannot be used by authorized person. The SMS notification is only applicable to the students. Significance of the Study 1. Students2. Professors This kind of system can now solve their problems in terms of dealing transactions and will achieve a safe learning environment, efficiency, security and accessibility of information. In add ition, this can help them fasten and lessen their work in every transaction.3. Proponents The study finds the proponent’s behavior in creativity of being a programmer. It is valuable because this will widen their knowledge and skills in programming and will encourage them to learn more about computer field.4. Access Computer College This will be a great advantage because Access Computer College will be known for its good education with regards in creating a program.Definition of Terms For better understanding of the readers, the following terms are defined: Accuracy – the ability of the system to be prà ©cised on its records and avoid errors. Database – Is an application that manages data and allows fast storage and retrieval of that data (en.wikipedia.org). Database helps the system to have a security in terms of storing information about a particular product or people. Efficiency – the ability of the system to achieve the desired result without wasted energy and effort. System – is a collection of automated transaction system (Microsoft EncartaDictionary, 2007).In this study, system refers to the Integrated Security with SMS Notification and Scanner for Access Computer College. Transaction – An agreement between a buyer and a seller to exchange an asset for payment (Webster Dictionary, William Collins, World Publishing Company Inc., 1990),the process of exchanging payments between the payment staff and the trainees. In this study, it is interaction between the students, professors and staffs having a transaction.CHAPTER IIMethod of Research Methodology includes the data gathering, Brainstorming, questionnaire, interviews, statistical treatment and testing activities.Data Gathering The following gathering data tools were used in this study.

Title: Estate Planning For the Elderly Course: TAX 6405-Gift, Estate, and Trust Taxation Table of Contents * Introduction * Power of attorney * Trusts * Wills * Joint ownership of assets * Lifetime gifts * Long term care insurance * Conclusion Introduction You may have heard a phrase like, â€Å"70 is the new 50.† There are large numbers of seniors living into their 80s and 90s. Estate taxation and planning has become a bigger concern, especially for baby boomers. There is a wide range of laws regarding the elderly and disabled. The law of the elderly and disabled has become more complex in recent years. Lawyers and financial planners who specialize in elder law assist with matters affecting the autonomy†¦show more content†¦A Health Care Power of Attorney should not be confused with a living will, even though both are considered Advance Health Care Directives. This is because instructions are given on what shall happen in the event that the person becomes unable to make future health care decisions on his/her own. A Living Will only allows the person to express his/her wishes concerning life-sustaining procedures. Health Care Power of Attorney becomes effective only when one does not have the capacity to give or withdr aw informed consent regarding one’s health care. General, special or health care power of attorney that contains special durability provisions is a durable power of attorney. For example, if a person becomes mentally incompetent while already having a valid power of attorney document, a durability provision will allow this document to stay in effect. Such a document can be signed to prepare for the possibility of a client becoming mentally incompetent due to illness or an accident. In this scenario, the power of attorney would not go into effect unless a doctor certifies that the person is mentally incapacitated. It is important to select someone of trust to be an agent. The durable power of attorney ends upon the death of the principal. In some states, if a spouse is the attorney-in-fact, a divorce will automatically terminate the durable power of attorney.
