List of Physics Formulas for JEE Exams: The Joint Entrance Examination (JEE) is one of the most competitive engineering entrance exams in India, conducted in two stages, JEE Mains and JEE Advanced. JEE Mains is held for a total of 300 marks, with Physics contributing 100 marks. The Physics section is divided into two parts: Section A, which contains multiple-choice questions (MCQs), and Section B, which includes numerical-based questions. A large portion of these questions are directly or indirectly based on formulas. 

This makes it essential for every aspirant to have a clear understanding of the key formulas and their correct application. Whether it’s Kinematics, Electrostatics, Thermodynamics, or Modern Physics, almost every concept in Physics involves one or more formulas that need to be remembered and used accurately. That’s why revising and practising the JEE Physics all formulas regularly can significantly improve your problem-solving speed and accuracy. In this guide, we have compiled Physics all formulas for JEE Mains in a simple and easy-to-read format to help you revise better and perform confidently in the exam.

List of Physics Formulas for JEE Exams

Go through the List of Physics Formulas for JEE Exams below:- 

Kinematics

Kinematics is the study of the motion of objects without considering the forces that cause them. It is one of the most fundamental topics in the Physics JEE formula sheet. This topic deals with linear motion, displacement, velocity, acceleration, and time. These are important formulas of Physics for JEE Mains that appear frequently in numerical problems.

  1. Final velocity:v = u + at

  2. Displacement:s = ut + 1/2 × a × t²

  3. Velocity-Displacement relation:v² = u² + 2as

  4. Displacement in nth second:Sₕ = u + (a/2)(2n – 1)

Freely Falling Bodies

This is a specific case of uniformly accelerated motion where the only force acting is gravity. These formulas are a key part of the JEE Physics all formulas list and help in solving problems related to objects dropped or thrown vertically.

  1. Final velocity:v = gt

  2. Displacement:s = 1/2 × g × t²

  3. Velocity-displacement relation:v² = 2gs

Projectile Motion

Projectile motion is a two-dimensional motion under gravity, combining both horizontal and vertical components. It is frequently asked in exams, making it a critical part of the Physics JEE formula collection.

  1. Time of flight:T = (2u sinθ) / g

  2. Maximum height:H = (u² sin²θ) / (2g)

  3. Horizontal Range:R = (u² sin2θ) / g

Work, Energy and Power

This topic deals with the concepts of work done by a force, different forms of energy, and power. These formulas are frequently used in both theoretical and numerical problems, making them part of the important formulas of Physics for JEE Mains. These Physics JEE formulas help in understanding energy conservation and mechanical work.

  1. Work done:W = F × d × cosθ

  2. Kinetic Energy (KE):KE = 1/2 × m × v²

  3. Potential Energy (PE):PE = m × g × h

  4. Power:P = W / t

  5. Power in terms of force and velocity:P = F × v

  6. Work-Energy Theorem:W = ΔKE

Rotational Motion

Rotational motion involves the movement of objects around a fixed axis. It includes angular quantities and is conceptually rich. It is an integral part of the JEE Physics all formulas list.

  1. Torque:τ = I × α

  2. Moment of Inertia:I = ∑ m × r²

  3. Angular Momentum:L = I × ω

  4. Rotational Kinetic Energy:KE = 1/2 × I × ω²

  5. Rolling Condition:v = r × ω

Gravitation

Gravitation focuses on the attraction between two masses and includes universal gravitational laws, acceleration due to gravity, and orbital motion. These formulas are must-know entries in any formula sheet for JEE Mains Physics.

  1. Gravitational Force:F = G × (m1 × m2) / r²

  2. Gravitational Potential Energy:U = – G × (m × M) / r

  3. Acceleration due to gravity:g = G × M / R²

  4. Orbital Velocity:v = √(G × M / r)

Properties of Matter

This section includes elasticity and mechanical properties of solids and fluids. Mastering these concepts and formulas is important for theoretical and problem-solving accuracy in JEE Mains.

  1. Stress:σ = F / A

  2. Strain:ε = ΔL / L

  3. Young’s Modulus:Y = σ / ε

  4. Pressure:P = F / A

  5. Pascal’s Law:P1 = P2

Thermodynamics

Thermodynamics deals with heat, internal energy, and the laws governing their interactions. It is a scoring topic and part of every JEE Physics all formulas revision list. These are among the important formulas of Physics for JEE Mains, particularly useful for conceptual and numerical questions.

  1. First Law of Thermodynamics:ΔQ = ΔU + ΔW

  2. Ideal Gas Equation:PV = nRT

  3. Work done in isothermal process:W = nRT ln(Vf / Vi)

  4. Adiabatic Process Equation:PV^γ = constant

How to Prepare for Physics in JEE

Physics is one of the most interesting yet challenging subjects in the JEE exam. It tests both your understanding of concepts and your ability to apply formulas in problem-solving. To do well in this section, students need a clear understanding of the syllabus, smart planning, and regular revision. Below are some important tips to help you prepare for Physics in JEE effectively.

1. Know the Exam Pattern and Marking Scheme

Before you begin your Physics preparation, it’s important to know how the exam is structured. The JEE Mains exam has three sections , Physics, Chemistry, and Mathematics, each carrying equal weightage. Understanding the number of questions, types of questions, and marking system helps you plan your time and effort more efficiently.

  • The JEE Mains paper is for a total of 300 marks, with Physics carrying 100 marks.

  • There are 30 questions in the Physics section – 20 are single-correct MCQs, and 10 are numerical-type, out of which only 5 need to be answered.

  • For each correct answer, you get +4 marks; for each wrong MCQ, –1 mark is deducted. Numerical questions have no negative marking.

2. Focus on Concepts, Not Just Formulas

Many students make the mistake of memorising formulas without understanding the concept behind them. Physics is a subject that requires clarity of ideas. Once your concepts are clear, using the formulas becomes much easier and faster.

  • Start with reading each chapter slowly and try to understand the logic behind each concept.

  • Watch videos or visual diagrams if you are finding any topic difficult to imagine or understand.

  • Try explaining the concept in your own words to yourself or to a friend.

3. Create Your Own Formula Sheet

One of the effective habits you can develop while preparing for Physics is to create your own formula sheet. A personal formula sheet for JEE Mains Physics will help you revise quickly, especially during the last few weeks before the exam. 

  • Write down all the important formulas of Physics for JEE Mains from each chapter in a notebook or a digital file.

  • Divide the sheet into topics such as Kinematics, Rotational Motion, Thermodynamics, and so on.

  • Use colours to highlight formulas that are difficult or commonly asked in questions.

  • Keep the sheet updated regularly after solving tests or revisiting concepts.

4. Practice Applying Formulas, Don’t Just Memories 

It is not enough to know the formulas, you must know how and when to use them. The application of formulas comes only with practice. Once you learn a formula, immediately apply it to different types of problems.

  • Solve a variety of problems from each topic after learning the concept and formula.

  • Practice derivations of a few key formulas to understand where they come from.

  • Try solving 5 to 10 formula-based questions every day to sharpen your speed.

  • Use online quizzes or flashcards to test your ability to apply physics JEE formulas under pressure.

5. Use Notes and Short Summaries for Quick Revision

The effective way to test your preparation is by solving previous year JEE papers and taking mock tests regularly. This not only helps you revise formulas but also improves your speed and accuracy.

  • Start solving previous year Physics questions after finishing each topic.

  • Take full-length mock tests to get a real feel of the exam environment.

  • Analyse your mistakes and correct them by going back to the formula or concept.

  • Make a list of physics JEE formulas you applied incorrectly and revise them separately.

  • Use a timer while solving questions to build time management skills.
