### Junior Intermediate Physics Chapter - wise Marks Weightage and Study Plan for 2017 - 2018

Every student who wants to study Physics seriously, must collect and revise frequently all the basic formulae with detailed description along with related units from all the chapters (Follow the prescribed text book for this task.) Don't forget that text book reading is mandatory. Keenly go through every paragraph of each chapter/ subtopic.

How to avoid Physics-O-Phobia?

Physics cannot exist without the continuous and compulsory support of Mathematics.
Mathematics is the back bone of Physics. A student who wants to get a glamourous score (especially in competitive exams like IIT-JEE, NEET, AIIMS, JIPMER, EAMCET etc.,) in Physics, must have thorough working knowledge of school level Mathematics. The algebra, the trigonometry, the geometry and elementary ideas from calculus are much needed.

Have good grip over the mathematical formulae from the above said topics to avoid, physics-O-Phobia. Finally remember "Mathematics is the Language of Physics."

Go through solved examples, Summary and points to ponder (given at the end of each
chapter.)

For answering objective questions in Physics successfully and rapidly in various competitive exams, every student must have sound knowledge in following areas: Angles, directions, conversion of units, ratios (percentage of changes) and hand rules (Right hand rule & left hand rule).

Derivatives & integrals.

Work seriously on various graphs related to the chapters (Chapters 3, 5, 8, 10, 12, 13 & 14 from Text book).

For fast calculations while answering objective questions it is worth remembering various physical constants in a easy way

5. System of particles and Rotational motion (Chapter 7)
6. Oscillations (Chapter 8)
7. Thermodynamics (Chapter 13)

One must have good grip on vectors (Addition, Resolution, Scalar multiplication with a vector, Dot Product & cross product).

First year chapters linked with Second year chapters:

Oscillations (Linked with Waves, Wave optics & Electromagnetic Waves of Second Year).

Motion in straight line, Motion in a plane, Work Energy & Power are core chapters which are connected to second year topics like motion of charged particle through electric, magnetic fields & their combined fields.

Thermodynamics, Thermal expansion of Gases & kinetic theory are chemistry overlapped chapters (one shot two birds!!)

Some useful tips for competitive exams:

Don't neglect the chapter like physical World, units & Measurements, Kinetic Theory.

From the chapter "Physical World," questions on fundamental forces of nature, contribution of Indian Scientists (Sir C.V.Raman, S.Chandra Sekhar, J.C.Bose, S.N.Saha, S.N.Bose, H.J.Bhabha) are expected.

Ex. 1. The correct ascending order of fundamental forces of nature is - (To answer this remember GWESi: Gravitational Force, Weak nuclear Force, Electromagnetic Force & Strong Nuclear Force is increasing order).

2. The discovery of C.V.Raman is "in the field of inelastic scattering of light by molecules of a medium (Raman effect)."

Concentrate on link between technology & Physics (Table 1.2 in page No. 7 of I Year Text Book July, 2017 edition).
