I have got an assignment from school about making an energy transformation model and I have no idea what to do!
Can you help me? (Posted by Maddy on 28 Aug 2011)
(Expecting suggestions from visitors and members)
There are many simple models for energy transformation. One of the themes for this years Science Exhibitions suggested by NCERT is “Energy Conservation”.
Any generator is a device for energy transformation.
You can think of any device which can convert energy from one form to another.
The IIT JEE Syllabus for Physics is available at http://jee.iitd.ac.in/physics.php
For preparation, the most important books you must study is the NCERT Physics for class XI and XII. Don’t get misguided by someone saying that the NCERT books are not worthy. Almost all the entrance examinations are depending on NCERT syllabus and books to set the standard. The NCERT text book has evolved as a result of strenuous effort of a group of hundreds of teachers from different parts of India and has been revised and updated after consultation and review workshop including teachers from every state. So, it is better to depend on it.
If you have mastered the book and can solve each and every exercise and additional exercise from the NCERT text book, then be glad that you have reached the level expected of you.
The next book you should take for reference is Fundamentals of Physics by Resnick and Hallidey. (This is the book many of the teachers and authors used to follow before the present revised edition of NCERT text book)
While preparing for IIT or any other competitive exams, it is important to understand the concept basically rather than to practice a large number of numerical problems.
A Chinese proverb says:
“Don’t give fish to a hungry man, teach him how to fish. He will not be hungry again!”
So, our aim is to practice the tactics and methodology with a strong foundation of the subject so that we can solve any type of conceptual or numerical problem.
Dare ask doubts to your teachers. (If you don’t dare, just post them here at www.askphysics.com ). Think and analyse facts yourselves and never depend on mere rot learning. Doubts pop up when you start thinking on what you learn. What you learn must be a part of your brain and life.
Wish you good luck
