NEET 2020 NEWS
NATIONAL LEVEL OFFLINE TEST
NEET 2018 is scheduled for May 6, 2018. With almost 2 months left for the exam, MBBS/BDS aspirants across the nation must be anxious regarding the preparation. Physics seems a very challenging section to most of the NEET aspirants. But, if prepared strategically, it can be cracked quite easily.
Physics in NEET is more conceptual rather than numerical. Topics like Mechanics, Heat & Thermodynamics, Electrodynamics and Modern Physics are the most important chapters for this exam. This selection of important areas is made on the analysis of previous years’ questions. Mugging up the theoretical part won’t help in clearing NEET Exam but understanding the concepts would.
In this article, you can find information about the most important chapters of Physics in NEET 2018 along with the weightage they hold. Apart from this, you may find information about important aspects of topics such as Light and Sound, Thermodynamics, Kinematics, etc.
Before jumping on to the preparation, you must be well versed with the pattern of the exam. Physics section in NEET comprises 45 questions wherein, each correct answer will fetch +4 marks and 1 mark will be deducted for every incorrect answer. Check NEET Exam Pattern
Physics has always made students uncomfortable with the complexities in both numerical as well as theoretical aspects. While preparing for NEET, often do candidates try and mug up all the topics given in NEET Syllabus, however, it is always wise to first sort them as per their weightage and level of difficulty. Given below are the most important topics of Physics which can be asked in NEET 2018:
The table below expounds upon the weightage and total marks from each unit and topic as is expected for the year 2018 in Physics section of NEET.

While preparing for NEET 2018, it becomes impertinent for candidates to get a clear picture of the important aspects of each unit, considering the commencement of both board preparation and NEET Preparation. So, given below are some of the useful tips on the most important chapters from Physics section of NEET 2018. CheckHow to Bridge Gap Between NEET and Boards Preparation
The foremost requirement is conceptual clarity. Before getting into the deeper analysis of any section, brush up your basics. Further, you can count on the topic-wise tips given below:
Work, Power & Energy: Understand the force. Deal with the Newton’s Laws of Motion and clear your concepts on conservative and non-conservative forces. HC Verma can help you in mastering the concepts of forces. While learning energy, keep in mind: “Energy can neither be created nor be destroyed, it can only be transferred from one form to another”.
Don’t forget the SI Unites. Power is Watt. Always try to balance the KE, PE and the work done. If you find yourself stuck in a situation then make use of Work Energy Theorem to eliminate one unknown.
Light & Sound: Both travel as waves but light travels faster than sound waves. The wavelength of sound ranges between 1cm to 10m and it easily diffracts around corners while the wavelength of visible light ranges from 400nm-700nm.
Sound waves are longitudinal that means particles of medium vibrate in a direction parallel to the propagation direction of wave. This can be seen in the following picture:
Light is a traverse wave and it can be understood by the following picture:
Understand and clear your concepts of wavelengths and learn by heart the wavelengths of lights.
Thermodynamics: Clear your concepts on zeroth law of thermodynamics, 1st law of thermodynamics, Joules’ law, kinetic theory & gases and principle of calorimeter. Practice the diagrams of Carnot engine, study its efficiency and coefficient of performance.
Gravitation: Simple questions on universal law of gravitation, variation of ‘g’, with altitude and latitude, energy conservation, orbital velocity and escape velocity should be focused to fetch more marks.
Kinematics: Displacement, acceleration, average velocity, relative velocity are the basics of Kinematics. Try to visualize the numerical/ concepts before solving. Generally, questions based on projectile motion are straightly asked, stick to the formulae.
Laws of Motion: Conceptual questions and applications on laws of motion are sure to come in NEET Exam. These can be prepared well by practicing free body diagrams. Finding velocity of the colliding body in 1D is important.
Properties of Bulk Matter: Be thorough with fluid mechanics, as it is interrelated to many other subtopics of NEET Physics such as Bernoulli’s Theorem and velocity of efflux. Clear concepts on stress, strain, poisson’s ratio, advantages of elasticity and behavior of wire under increasing load can help you score better in NEET exam.
NCERT Books are considered best for understanding the concepts. And most importantly, most of the questions are picked from NCERT books in NEET exam. Practicing questions from other reference books will greatly boost up the preparation. Given below is a set of reference books for NEET Physics preparation.
