NEET Physics Formula Sheet: Chapter-Wise Compilation

NEET Physics Formula Sheet: Chapter-Wise Compilation

The NEET Physics syllabus is split almost equally between Class 11 and Class 12, and it covers close to 20 chapters in total. Not every chapter deserves the same attention, though. Chapters like Mechanics and Current Electricity repeat in the exam year after year. Others, such as Semiconductors or Communication Systems, are shorter but still worth knowing well, because a scoring chapter is a scoring chapter no matter how small it looks on paper. Below, you will find formulas grouped chapter-wise, starting with Mechanics.

NEET Physics Formula Sheet: Mechanics Formulas

Mechanics is where most students begin their Physics preparation, and honestly, it is also where most numerical-solving skills get built. It includes Kinematics, Laws of Motion, Work Power Energy, and Gravitation, and together these chapters have consistently been among the more heavily tested areas, as you will notice in the NEET Physics Chapter-Wise Weightage breakdown of past years' papers.

• Equations of motion: v = u + at, s = ut + ½at², v² = u² + 2as

• Newton's second law: F = ma

• Work done: W = F × s × cosθ

• Kinetic energy: KE = ½mv²

• Power: P = W/t

• Universal law of gravitation: F = Gm₁m₂/r²

• Escape velocity: v = √(2gR)

• Centripetal force: F = mv²/r

If there is one section you should never rush through, it is this one. Nearly every other chapter borrows something from Mechanics, so getting comfortable here early makes the rest of your preparation noticeably smoother.

NEET Physics Formula Sheet: Heat, Thermodynamics and Oscillations

These three chapters, Thermal Properties of Matter, Thermodynamics, and Oscillations, do not get talked about as much as Mechanics or Electricity, but they quietly contribute a fair share of questions every year.

• First law of thermodynamics: ΔQ = ΔU + ΔW

• Ideal gas equation: PV = nRT

• Efficiency of a heat engine: η = 1 − (T₂/T₁)

• Time period of a simple pendulum: T = 2π√(l/g)

• Time period of a spring-mass system: T = 2π√(m/k)

• Wave speed: v = fλ

A lot of students lose marks here not because the formulas are hard, but because of careless mistakes with signs and conventions in thermodynamics numericals. Slowing down a little and sticking to a proper revision routine, like the one outlined in our NEET Preparation Tips article, can help you avoid that.

NEET Physics Formula Sheet: Electricity and Magnetism

Current Electricity, Magnetism, and Electromagnetic Induction are often clubbed together as one of the heaviest sections in the entire NEET Physics paper, and for good reason.

• Ohm's law: V = IR

• Power in an electrical circuit: P = VI = I²R

• Resistors in series: R = R₁ + R₂ + R₃

• Resistors in parallel: 1/R = 1/R₁ + 1/R₂ + 1/R₃

• Coulomb's law: F = kq₁q₂/r²

• Magnetic force on a moving charge: F = qvB sinθ

• Faraday's law of induction: ε = −N(dΦ/dt)

What makes this section a little easier than it looks is how repetitive the question patterns are from year to year. Going through the NEET Physics Question Paper of the last few attempts will show you exactly what kind of numericals to expect.

NEET Physics Formula Sheet: Electrostatics and Semiconductor

Electrostatics is where Current Electricity really begins, so getting this right first makes the later chapter easier to follow. Semiconductor Electronics, on the other hand, is short enough that a lot of students end up skipping it, which is honestly a mistake since it is one of the more scoring chapters if you actually sit down and learn it.

• Electric field due to a point charge: E = kq/r²

• Electric potential due to a point charge: V = kq/r

• Capacitance of a parallel plate capacitor: C = ε₀A/d

• Energy stored in a capacitor: U = ½CV²

• Capacitors in series: 1/C = 1/C₁ + 1/C₂ + 1/C₃

• Capacitors in parallel: C = C₁ + C₂ + C₃

• Diode current equation: I = I₀(e^(qV/kT) − 1)

Most Electrostatics questions in NEET are fairly direct once you know the formula, so this is a good place to pick up quick marks without spending too much extra time.

NEET Physics Formula Sheet: Optics and Modern Physics

Ray Optics, Wave Optics, and Modern Physics tend to be everyone's favourite chapters by the time exam season rolls around, mainly because the formulas are straightforward and the questions rarely try to trick you.

• Mirror formula: 1/v + 1/u = 1/f

• Lens formula: 1/v − 1/u = 1/f

• Lens maker's formula: 1/f = (n − 1)(1/R₁ − 1/R₂)

• Young's double slit fringe width: β = λD/d

• Photoelectric equation: hν = φ₀ + KEmax

• Energy of a photon: E = hν = hc/λ

• Radioactive decay law: N = N₀e^(−λt)

Understanding where a formula comes from, even briefly, makes it stick far better than memorising it blindly. Combine that with the right study material, and revision gets even faster. Our Best Books for NEET guide is a good place to check if you are still deciding what to study from.

How to Use This NEET Physics Formula Sheet for Quick Revision

Having a formula sheet is one thing. Actually using it well is a different skill altogether, and it is where most students fall short. A few things that genuinely help:

• Do not just stare at the formulas. Write them out by hand at least once so your memory has something to hold on to.

• Revise chapter-wise, a little at a time, instead of trying to cram everything into one long session the night before.

• The moment you learn a formula, solve two or three questions built around it. That is what actually makes it stick.

• Keep a small, formula-only notebook for the last few days before your exam, with no long explanations, just the equations themselves.

• Always double-check units and signs. A surprising number of marks in NEET Physics are lost not because a student didn't know the concept, but because of a careless sign error.

Even 20 to 30 minutes of this kind of focused revision daily adds up faster than most students expect.
