GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods

Justification for scheme of work 0805064 Angie Newton Planning as a whole is an essential aspect of teaching and is even more effective when it’s a process that is collaborative with your colleagues and pupils‚ therefore enhancing the effectiveness of your teaching (DCFS‚ 2011‚ Mawer‚ 1995). Schemes of work are a long term planning solution‚ which identify the learning opportunities across a whole school year (Gower‚ 2004). The framework is broad‚ so to go alongside the scheme of work‚ units of

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including

Factors/Explanation of a Job Evaluation Scheme: A job evaluation scheme is “a method to determine the value of each job in relation to all jobs within the organization.” A job evaluation process is useful because sometimes job titles can be misleading- either unclear or unspecific- and in large organizations it’s impossible for those in HR to know each job in detail. The use of job evaluation techniques depends on individual circumstances. Job evaluation is often used when: establishing

The fundamental forms of energy are kinetic‚ potential‚ and thermal energy. b. Most of the time will be spent understanding the transforming of energy. c. Energy can be transformed by applying a mechanical force. d. The law of conservation of energy‚ energy is neither created nor destroyed‚ is consider by scientists to be the most important law of

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

You throw the ball. You catch the ball‚" said a well-respected baseball manager by the name of Casey Stengel. Mr. Stengel was a baseball man‚ not a mathematician nor a physicist. Physics and mathematics can be applied to the game of baseball on every pitch‚ and on every swing of the bat. To understand the physics of the game‚ it is first necessary to look at the center of the game‚ the ball. Section 1.09 of the Official Baseball Rules states that the ball must weigh between 5 ounces and 5 ¼

Is NREGA(National Rural Employment Guarantee Act) a success or a failure? The NREGA is an Indian Job Guarantee scheme‚ enacted by the legislation on Aug 25‚2005. The scheme provides a legal guarantee for one hundred days of employment in every financial year to adult members of any rural household at a wage of Rs 120 per day. So almost after five years of its commencement can NREGA be considered a success ? This essay will consider a number of explanations for concluding the impact of NREGA. My
