Complete JEE Main Physics Formula Sheet 2026

A well-organized formula sheet is the single most powerful last-mile revision tool in Physics. In the final weeks, you have no time to re-read textbooks, but a five-minute daily pass over your formulas keeps hundreds of relations instantly accessible. This guide shows you how to build and use a formula sheet that actually improves your score, organized by chapter the way the exam thinks.

Why a Formula Sheet Beats Re-Reading

The mistake most students make is treating a formula sheet as a passive list. The version that works is annotated: every formula sits beside the exact condition under which it holds. The kinematics equations only apply to constant acceleration; the isothermal work formula only applies when temperature is fixed. Writing these conditions transforms a memory aid into a thinking tool that prevents the classic exam-day misapplication.

Build the sheet yourself rather than downloading one. The act of writing each formula, deriving it once, and noting its condition is what cements it. A borrowed sheet is someone else's memory, not yours.

Mechanics and Thermodynamics

The mechanics section is the largest: kinematics equations, Newton's laws, work-energy theorem, momentum conservation, and the rotational analogues including moment of inertia and angular momentum. Group the linear and rotational formulas side by side to reinforce the analogy. Thermodynamics adds the first law, the four-process work expressions, and the specific-heat relations. Reviewing our mechanics master guide alongside this section makes the formulas meaningful rather than abstract.

Once your mechanics section is complete, take a free mock test and use the sheet only for review afterward, never during, to build true recall.

Electrodynamics and Modern Physics

Electrodynamics is the most formula-dense area: Coulomb's law, field and potential expressions, Gauss's law, capacitance, Ohm's law, Kirchhoff's rules, the Biot-Savart and Ampere results, and the induction laws. Organize these so the electric and magnetic parallels are visible. Modern physics, by contrast, is lean: the photoelectric equation, Bohr-model relations, the de Broglie wavelength, and the radioactive-decay law cover most of it.

Because modern physics is so compact, it is the easiest section to revise daily and the most reliable to score, as our modern physics guide explains in detail.

How to Use the Sheet Daily

Spend five minutes every morning reading the entire sheet, then test yourself by covering the formulas and reciting them. In the last week, focus extra passes on the chapters where your mock errors cluster. The sheet is a living document; add to it whenever a mock reveals a formula you did not have at your fingertips.

A great formula sheet does not replace understanding, but it makes your understanding instantly accessible under exam pressure. Build it carefully, annotate every condition, and revise it daily. Combined with the 30-day revision plan, it becomes the backbone of your final-month preparation.
