How to Study Laws of Motion Effectively for JEE Mains 2026?
Here is a shortcut to study Laws of Motion more effectively for JEE Mains 2026.
- 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.
Theorem | Equation |
|---|---|
Impulse-Momentum Theorem | J = Δ p |
Work-Energy Theorem | Wnet = ΔKE |

FAQs
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.
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.
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.
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.
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.
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.
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.
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.
