Start Preparing for Physics for JEE 2016

Physics is probably the subject which JEE aspirants appreciate the most because physics is what we can see in our daily life. Physics is something that explains our observations. The most important topics in Physics are:

Mechanics: Physics starts with probably the most important topic any engineer should know – Mechanics. If you are an engineer, you simply cannot ignore mechanics. You SHOULD know the statics and dynamics of the objects around you and you should be able to explain various physical phenomena.

JEE mechanics talks about some of the most fundamental laws – Newton’s laws of motion, universal law of gravitation, law of conservation of linear momentum, law of conservation of energy and their rotational equivalents. These laws form the frame work of physics and every student is expected to know them properly. Students *must* be able to apply these laws to a wide variety of situations.

Just remember – whenever you see a mechanics problem, brainstorm this list:

  • Newton’s laws
  • Work energy theorem
  • Law of conservation of energy
  • Law of conservation of momentum (linear/angular)
  • Equation of continuity
  • Bernoulli’s theorem

The 4 laws/theorems mentioned above plus your own knowledge/experience will suffice to solve almost any JEE level mechanics problem. Pro tip: do not ignore the chapter on elasticity

Fluids and waves and sound: A lot of questions are asked from waves and sound; the most common ones are from Doppler Effect. Practice ample of questions from fluid mechanics as well. Remember the 2 important results of fluid mechanics:

Thermal physics:this chapter indeed covers a big chunk of the paper. Since the topics are diverse, don’t be surprized to see a question which is a mix of calorimetry with the laws of thermodynamics. Familiarize yourself with calculations of work, internal energy and heat in various processes.

Electricity and magnetism: They includes the biggest section of JEE paper as lots of questions are asked from the applications of Coulomb’s law. Capacitance is another favourite topic. Make sure to stick to JEE syllabus because this topic is diverse. Spherical and Cylindrical capacitors are not in JEE syllabus presently. Don’t be scared of complex circuits and try to use the fundamentals to reduce complicated circuits to simpler ones. Use Kirchhoff’s laws, use series parallel reduction. Do not ignore the theoretical aspects of the topic. There are quite a large number of standard formulae in electrostatics and magneto statics. Make sure to remember them all (with directions involved) because you won’t have enough time to derive standard results on THE day.

Faraday’s laws: A lot of questions are asked from this. Motional EMF is one of the most asked topics in JEE so ensure that you practice ample of questions from it.

Potentiometer related experiments:Do not ignore this topic asJEE contains questions involving error analysis pertaining to potentiometer related experiments so make sure to understand them.

Optics: It is another seemingly difficult topic, however, if good numbers of questions are practiced, it can be one of the simplest topics. It is important to not ignore Huygen’s principles. A paragraph was asked in JEE recently from Huygen’s principles, highlighting the fact that good students cannot ignore it.

Modern physics:It is mostly theoretical; in this, the focus should be on understanding the nuances of Bohr’s model. The common formulae should be memorized.

Practice ample of questions, read standard books, solve past year papers – that’s all you need to do well in JEE physics
