How to Study Laws of Motion Effectively for JEE Mains 2025?

Here is a shortcut to study Laws of Motion more effectively for JEE Mains 2025.

  • In-depth study of Newton’s Law of Motion

Laws

Shortcut

First Law (Law of Inertia)

Fnet = 0 Body is either moving in constant velocity or is at rest

Second Law (F = ma)

Use free body diagrams

Third Law (Action-Reaction Law)

Consider pair of forces

  • Free Body Diagrams are always advisable

For questions based on forces, always use free-body diagrams to identify and label forces like weight, friction, applied force, and tension.

  • Friction Forces

Forces

Equations

Kinetic Friction

Fk = μkN

Static Friction

Fs ≤ μkN

  • Capitalise on Work-Energy and Impulse-Momentum Theorems whenever required

Use these theorems when forces are not constant or when time is not at all given.

FAQs

Is HC Verma enough for the JEE Main Physics preparation?

HC Verma is an important book for the JEE Main preparation as it comprises good explanations and many practice problems. But it is not enough to solely rely on it. Candidates are required to study NCERT textbooks as well.

Is the JEE Main syllabus reduced?

In the reduced syllabus of the JEE Mains exam, most topics have been removed from Chemistry with 6 units completely removed and around 20 topics removed from 5 other units.

 

Can candidates skip chapters in the JEE Main exam?

Though it's not wise to skip any topic for the JEE Main exam, however, if one is short on time, candidates can leave low-weightage topics and invest their time on the  important topics.

 

 

Can candidates get admission into NIT with 92 percentile in JEE Main?

If the candidates are seeking to get admission into the top-listed IIITs, and NITs, then it will be difficult for them with such a percentile score. However, the reserved category candidates can try their luck to get admission into the IIITs or NITs with 92 percentile marks.

 

Which is the hardest chapter in JEE Main Physics exam?

The hardest topics in the JEE Main Physics exam comprise Heat and Thermodynamics, Electrostatics and Magnetism, Mechanics, Modern Physics, Current Electricity, Optics, and Electromagnetic Induction.

 

Are previous year question papers enough for the JEE Main exam?

No. Candidates should base their JEE Main exam preparation on the previous year's question papers, mock tests and practice tests to ace the JEE Main exam with high marks.

 

 

Is it easy to score 170 in the JEE Main exam?

170 marks in the JEE Main exam equals to 98.85+ percentile, which in itself is a very good percentile. Through this, candidates can secure admission into the top premier institutes in India such as NITs, IIITs, and GFTIs.

 

 

Which topics have more weightage in the JEE Main Physics paper?

In the JEE Main Physics paper, chapters with the most weightage are Electrostatics, Optics, Current Electricity, and Mechanics whereas the moderate weightage chapters comprise Magnetism, Modern Physics, Waves, and Thermodynamics.
