## Physics- Part-2

We discussed in the last article the importance of physics as a subject. We also saw that knowledge of physics is essential for understanding other sciences as well. Now comes the real question: How to start studying physics?

PREREQUISITE
For studying physics you must have good knowledge of mathematics and geometry. Mathematics is the language of physics so a student of physics is required to study lots of mathematics (concurrently with physics) to be able to understand physics.
You must have the tendency of understanding things.Some people think that they will manage by learning (memorizing facts) in physics. I would like to tell it very clear to such people that learning without understanding will not be of much help in physics. Success in physics is possible only for those who have a strong tendency to understand things.
You must be able to draw and understand GRAPHS for situations that you analyse in physics. Graphs help us to better visualize a situation.
Very often you will be required to draw diagrams to visualize and better understand a
situation.

How to Begin
It has been experienced by scientists that every phenomenon of nature is directly or indirectly related to motion of some particle, object or to some radiation (which is again wave motion).For example, Chemical reaction is rearrangement of atoms (which is possible only if atoms move).When we touch a hot kettle and we feel its hotness,that becomes possible only because atoms of the kettle are vibrating more vigorously than atoms of our hand, and by touching our hand to the kettle we allow the atoms in our hand to come into intimate contact with atoms of the kettle body. When this happens the atoms of the kettle transfer some of their kinetic energy to those atoms of our hand which are touching them. Thus those atoms in our hand begin to vibrate with greater average speed. This generate a sensory wave that travels from the hand to the brain. The brain interprets the incoming sensory wave as the perception of hotness. Similarly all climatic phenomena depend upon the wind flow. We can cite unending list of examples to support the fact that motion is behind every phenomenon
of nature.
So it is very important that we develop a very thorough understanding of motion before trying to understand other phenomena of nature. That is why the study of physics as a subject starts with studying MECHANICS,which is the physics and the maths of analysing motion. My suggestion to you is that you should make all your efforts to develop a proper understanding of MECHANICS.

You will be required to have a fair knowledge of Algebra, Coordinate Geometry, Trigonometry, Vector Algebra, Differentiation and Integration etc. in maths, to be able to understand Mechanics well. A good physics teacher will concurrently teach you the essentials of all these topics in maths to
enable you to understand Mechanics.

Read Part-1and Part-2 of my articles. If your state board books are good then there is no need to study NCERT books.

NCERT books are the best books for the Indian context. They contain the entire syllabus in a compact manner. Yes, in the beginning you may find the language of NCERT a little tough but if you continue to study from it then after some time you will have no problem. But more than any book you should look for a good teacher of each subject.Because if a good teacher teaches you any concept then to you that concept becomes very easy.

Frankly speaking, I like physics; however I haven't been able to develop that problem solving tactic which is required in physics. I'm studying Motion In a Straight Line and there are certain questions where the details of motion of different objects are combined together e.g. say, a question based on a thief and a police. I really find it very difficult and I also know that I cannot be complacent with the simpler questions that are asked in school exams.I would like to know what approach is necessary to solve such problems whose concept is clear to you but you are unable to analyse the situation and solve the question properly.

Anonymous,
try to express the position of each moving object as a FUNCTION of time.That is, study motions through FUNCTIONAL approach. Then try to find the time at which the two position functions have same output.

Get personal tuition in physics from some good teacher for more help.

HCV has good collection of solved examples and exercise problems for giving you good practice for entrance exams.
SLAr is a good book for being used as a supplement to the NCERT book for board exam.

Anonymous writes: Sir, I am preparing myself for medical entrance exams to be held in the year 2013. You stress a lot on the importance of NCERT textbooks. True that the entire syllabus for JEE is based on these books. However, none of the questions from NCERT are ever asked in any competitive exam. At times, I feel that questions from NCERT are way too tough, especially in Mechanics. Other reference books provide much easier questions. My query is that a few questions of NCERT require memorizing steps (the lengthy ones - As an example Que 3.26 of Class XI Physics part - I) I felt that solving that question the usual way never yielded answers and the solution provided by reference books had a slightly different approach. Are they all that necessary ?

J.P.Sinha jyopra Thursday, April 12, 2012 4:23:39 AM

NCERT books are the base of all the entrance exams. You are finding the questions asked in the NCERT tough, this means you have not understood the concepts in physics well. Or may be your teacher is not explaining you the proper way of problem solving.
Yes, if you are not comfortable with the NCERT books then use that book which you like studying from. Main thing is to master the subject.

hello sir, i am presently studying in class 12 and i haven't joined any coaching institute for iit jee preparation. sir, i just got 70% in my class 11 which is quite less. so, i would like to know which books i should refer to for physics, chemistry and maths other than ncert to ensure a good rank in iit jee. sir, i also want to know how should i study now so as to revise my entire 11th syllabus too.. sir please give me some routine tips.
thanks

Procure this year IIT-JEE's paper and study the subjects to gain capability of solving questions like that. Apart from NCERT text books you can use one IIT-JEE guide in each subject. Click here to read an article on general study techniques.

thanks for replying, but, sir, what refreshers i should choose to understand a topic better?

J.P.Sinha jyopra Wednesday, April 18, 2012 10:36:49 AM

Soumya
To understand a subject better you need the services of a good teacher. Books, without a teacher, will not be of much help.

sir can you please tell me which is more better hc verma or resnick halliday in physics?
and tmh or kc sinha in maths?
thanks

J.P.Sinha jyopra Tuesday, April 24, 2012 6:05:11 AM

H C Verma is better because it is according to the Indian syllabus. K.C.Sinha is good for reference book and TMH is a good guide. NCERT is the basic text book.

No book in India right now is very good at clarifying the basics.

But ,in physics, I have seen that some of the proofs of derivations given in reference guides or by tuition teachers seems to be easier.Will I get marks if I study such derivations for board exam? Also, I have not prepared for the XII board that is fast approaching. Am I too late to start learning to get good marks? Or will I be able to take an improvement exam? Thank you
