JEE Main Formula Sheet: Candidates preparing for the upcoming JEE Main 2026 exam must have a solid grasp of all mathematical identities, physics constants, and chemistry reactions. As the JEE Mains syllabus is vast, experts advise students to maintain a consolidated PDF of all formulas for IIT JEE to streamline their revision process. According to previous year trends, a significant number of questions in the JEE Main exam are formula-based, and having these at your fingertips can significantly improve your speed and accuracy.
Candidates are advised to use these sheets as a "cheat sheet" during their final revision phase. Below, you will find the topic wise formula list for JEE Main physics, key calculus formulas to revise for JEE Main maths, and essential chemistry equations to memorise for JEE Main.
To crack JEE Main 2025, efficiency is key. Instead of scanning through multiple thick textbooks, candidates are advised to use a consolidated PDF of all formulas for JEE Main. This "one-stop" resource eliminates the need for manual note-taking and ensures that no critical identity is missed during high-pressure revision.

Physics in JEE Main is increasingly becoming formula-centric with a focus on direct applications. To score high, candidates must prioritize Mechanics, Electrodynamics, and Modern Physics. This JEE Main Physics formula list covers the essential identities required to solve numerical problems quickly.
| Unit | Key Formulas to Memorise |
| Thermodynamics | First Law (ΔQ = ΔU + ΔW), Carnot Engine Efficiency |
| Current Electricity | Ohm's Law, Drift Velocity, Potentiometer Sensitivity |
| Rotational Motion | Moment of Inertia of standard bodies, Angular Momentum |
| Gravitation | Escape Velocity (ve = √(2GM/R)), Kepler's Third Law |
Calculus accounts for nearly 25-30% of the Mathematics section. Mastering these identities is essential for candidates aiming for a high percentile.
Expert Tip: For Maths, don't just memorize; practice the application of key calculus formulas to revise for JEE Main maths through at least 5-10 PYQs per topic.
Chemistry is often the highest-scoring section in JEE Main. While Physical Chemistry requires numerical accuracy, Organic and Inorganic sections demand a high level of retention. Below are the essential chemistry equations to memorise for JEE Main categorized by branch.

Most important chapters for JEE Main Physics formulas are Modern Physics, Electrodynamics, Thermodynamics, and Mechanics because these areas collectively contribute a large share of formula-heavy questions. Important Physics chapters for formula mastery
| Topic Area | Key Formula Focus |
| Modern Physics | Photoelectric effect, atomic models, energy levels |
| Electrodynamics | Gauss’s law, Kirchhoff’s rules, EMF concepts |
| Thermodynamics | Laws of thermodynamics, heat engines, entropy |
| Mechanics | Motion equations, work-energy, rotational dynamics |
The 2026 formula sheet reflects the updated JEE Main syllabus, removing topics officially deleted (such as Mathematical Reasoning and specialist modules like Metallurgy) and aligning strictly with the current NTA syllabus. Changes mean the 2026 sheet is not identical to 2025.
Universal gas constant values commonly used in JEE Chemistry problems:
| Unit Form | Value |
| R (J·mol⁻¹·K⁻¹) | 8.314 |
| R (L·kPa·mol⁻¹·K⁻¹) | 8.314 |
| R (L·atm·mol⁻¹·K⁻¹) | 0.08206 |
These are standard constants for gas equations like the ideal gas law (PV = nRT) used in calculation-based questions.
Effective memorization over 30 days uses a rhythm of active recall and spaced revision with short daily sessions. Focused sessions of 15–20 minutes per subject with a printable master formula sheet help lock key relations into memory. Cycle through Physics, Chemistry, and Mathematics formulas repeatedly while testing recall rather than passive reading.
Recommended daily approach
| Day Blocks | Focus Type |
| Days 1–10 | Core formula learning |
| Days 11–20 | Application problems using formulas |
| Days 21–30 | Mixed revision + timed recall tests |
Create a compact formula book by segmenting content by subject (Physics, Chemistry, Mathematics). Within each section, include only final results, exceptions, common numeric constants, and standard units. Exclude extended derivations to maintain brevity. Structure recommendation
| Section | What to Include |
| Physics | Standard equations, units, symbols |
| Chemistry | Constants, equations, reaction trends |
| Mathematics | Key identities, integrals, standard limits |
In JEE Main, final formula recall and application speed are more valuable than full derivations. Derivations help conceptual depth but can limit time efficiency. Focus primarily on formula familiarity and direct substitution skills for maximum scoring potential in the time-bound environment.
Formula sheets are essential tools, but scoring full marks in Maths requires application practice, particularly through solving previous year questions and mock tests. Formula recall assists in swift setup, but correct problem solving under timed conditions determines actual performance.
Chapter-wise formula lists for JEE Main Physics can be accessed via the official downloadable PDF links embedded within many subject-specific pages on coaching and preparation portals. These PDFs often group formula sets by topic and include quick-reference tables for rapid revision.
Standard calculus formulas that recur frequently include:
These support typical JEE Main calculus problems and are foundational in solution steps.
