Q. HOW MANY FORMS OF ENERGY?

Q. HOW MANY FORMS OF ENERGY ARE THERE?

ANS. I think there are only 4 forms of energy type at fundamental level, as described below:

1. Relativistic Mass & Kinetic Energy : Which is sum of Kinetic Energy and Rest mass energy.
  So Relativistic Energy = K.E.+ Rest Mass Energy =  1/2 x m₀v² + m₀c²
                                               = mc<sup>2

It is also given by</sup>  

2. Potential Energy : Which is due to interaction of a particle with other particles or fields.
  There are various types of potential energies, e.g. Gravitational, Electromagnetic, Nuclear etc.

3. Dark Energy : Which is as the name suggest we are not able to understand at all. We don't know what is its nature, what is its source, how it convert from one form to other forms. Only thing that we know about the Dark Energy is that, it is there. Whenever we see a change in total energy of a system without any reason it may be due to Dark Energy being converted to other known forms of energy or vice-versa. E.g. Our universe is accelerating, means our K.E. is increasing and we are not able to explain it pointing towards Dark Energy.

Who should study in US Universities?

The average fee of US universities is very high, 10-20 Lacs Rs./Year.
I would recommend US Univerisity for the following category:

• For those whose parents can afford paying 10-20 Lacs/Year
• For students who can get scholarship

US universities are good for the following courses:

• Courses in Pure Science
• Arts, Commerce and Law
• Management courses

Note : If you can get admission in IITs/NITs or Good medical colleges I will not recommend 

to go to US Universities even IITs are ranked very low in Top Universities, becaz in IIT you will be 

studying with the very intellectual group of students.

What is ACT test ?

The ACT® (American College Testing Assessment) is paper based standardized test which can be given instead of the SAT® for admission in the United States for undergraduate studies. The ACT® is based on the curriculum studied in high school. General Overview: The ACT® is 3 hours and 30 minutes long and tests the student in four subject areas: English, Reading, Math, Science Reasoning, Writing (optional). In India, the ACT® is conducted 5 times a year in February, April, June, October and December. Scoring for the ACT® is on a scale of 1-36 and includes 215 multiple choice questions on the subject areas.  Registration for the ACT® requires a valid passport, an exam fee of US $33 (without writing) or US $ 48 (with writing). Registration can be done on: www.actstudent.org

The Content:

English: It is a 45-minute section with 75 questions. The English section includes five passages that are followed by multiple-choice questions. The test measures grammar usage, sentence structure, punctuation and overall correct use of English language.  Math:It is a 60-minute section with 60 questions. In this section, students are tested in basic arithmetic, algebra, geometry, trigonometry, etc through multiple-choice questions that require you to use reasoning skills to solve practical problems in mathematics. You are allowed to use certain calculators on the test.  Reading: It is a 35-minute section with 40 questions. It includes four passages on topics like the natural and social sciences, psychology, history, etc. These passages are followed by multiple-choice question thatmeasure the complementary and supportive skills that readers must use in studying written materials across a range of subject areas. The section measures the test taker’s ability to understand what is directly stated and decipher statements with implied meanings.  Science: It is a 35-minute section with 40 questions. The section includes seven passages containing questions on data presentation. It also includes experimental studies and their results, and different theories or hypotheses relating to specific scientific concepts. The test measures the skills required in the natural sciences: interpretation, analysis, evaluation, reasoning, and problem solving.  Writing (optional): It is a 30 minute section that consists of a writing prompt that briefly states an issue and describes two points of view on that issue.You are asked to respond to a question about your position on the issue described in the writing prompt. In doing so, you may adopt one or the other of the perspectives described in the prompt, or you may present a different point of view on the issue.The section measures your writing and analytical abilities.

What is SAT subject Test ?

The SAT® Subject Tests (Scholastic Aptitude Test II) are completely different from the SAT® reasoning test. Strong SAT® Subject scores strengthen your application and complement the SAT® reasoning score. It shows colleges and universities that you excel in certain subjects. SAT® subject test is a one-hour timed test focused on a specific subject. There are 20 SAT® Subject Tests in five general subject areas: English, History, Languages, Mathematics and Science.  The test is administered six times a year in India and may be attempted more than once. Language Tests with listening are offered once a year, in November only. Different schools have different SAT® score requirements. Your scores better your chances of getting admission into a particular U.S. university. Registration for the SAT® requires a valid passport and can be done on www.collegeboard.org.

The Content: At KIC, SAT® Subject test coaching is offered in:

Mathematics Level 1:

Mathematics Level 1 is a test measured on a scale of 200 – 800. It is 60 minutes long with 50 multiple-choice questions. The questions test a student's ability and skills on topics like number and operations, algebra and functions, geometry and measurement, three-dimensional problems, trigonometry, data analysis, etc.

Mathematics Level 2:

Mathematics Level 2 is a test measured on a scale of 200 – 800. It is 60 minutes long with 50 multiple-choice questions. The questions test a student's ability and skills on topics like number and operations, algebra and functions, geometry and measurement, three-dimensional problems, trigonometry, data analysis, etc just like Mathematics Level 1 test. However, if you have studied trigonometry or precalculus or both in the recent past and are more comfortable using a scientific or graphical calculator, it is advised you take Mathematics Level 2 test. It is also important to consider what your college and course demands.

Biology E/M:

Biological E (Ecological) and Biology M (Molecular) are both measured on a scale of 200-800. They are both 60 minutes long with 80 multiple choice questions each. If one is better at answering questions in areas of biological communities, populations and energy flow, he/she should take Biology E. If one is better at answering questions in areas of biochemistry, cellular structure and processes, such as respiration and photosynthesis, he/she should take Biology M.

Chemistry:

Chemistry Subject test is measured on a scale of 200-800. It is a 60 minutes long exam with 85 multiple choice questions. It tests a student's knowledge in areas of general chemistry like states of matter, descriptive chemistry, stoichiometry, thermochemistry, equilibrium and reaction rates, etc.

Physics:

Physics Subject test is measured on a scale of 200-800. It is a 60 minutes long exam with 75 multiple choice questions. It measures a student's ability to apply physical concepts to solve scientific questions. It also tests a student's knowledge in metric system of units.
