NEET UG 2026 Physics Formula Sheet: Physics in NEET UG is a scoring subject only for those who have command of formulas. Students who memorise and practice the application of formulas typically score 120+, even without heavy conceptual depth. On the other hand, students who struggle with formula recall often lose marks.
This article presents an extremely comprehensive, elaborate, and chapter-wise compilation of the 150 most repeated Physics formulas asked in NEET (2015-2024). It explains where they come from, why they matter, their PYQ frequency, and how they shape your NEET preparation.
If you are preparing for NEET UG 2026, this is one of the most important resources you will read today.
Why Formulas Dominate NEET Physics
There are three key reasons:
NEET Physics = Formula Substitution
Almost 70-80% questions directly require formulas:
Join NEET News 2025 - Mechanics numericals
- Optics calculations
- Capacitors
- Current electricity
- Modern physics
Formula Patterns Repeat Every Year
If a formula is asked once, NEET asks it again and again across multiple years. For example:
- Mirror formula
- Lens maker formula
- Coulomb’s law
- Work-energy relation
- de Broglie equation
These formulas dominate the question papers because they form the basis of simple, standard MCQs.
Formulas Reduce Fear in Physics
Students fear Physics mostly because they lack the proper method. Once formulas are organised chapter-wise and revised repeatedly, the fear disappears.
You start solving questions in 10-15 seconds, which boosts confidence drastically.
The Weightage of Formulas (Chapter-Wise Trend)
A quick look at how NEET distributes marks across chapters:
| Chapter | Approx Weightage | How Formula-Dependent It Is |
|---|---|---|
| Mechanics | 25-30% | Extremely High |
| Work, Power, Energy | 8-10% | High |
| Rotational Motion | 6-8% | Very High |
| SHM & Waves | 7-8% | High |
| Thermodynamics | 7-9% | Very High |
| Electrostatics | 6-7% | Extremely High |
| Current Electricity | 6-8% | High |
| Magnetism | 6-7% | High |
| EM Induction | 4-5% | Very High |
| Optics | 10-12% | Very High |
| Modern Physics | 12-15% | Extremely High |
From this, it’s clear that the majority of chapters require quick recall of formulas rather than long derivations.

NEET UG 2026 Physics Formula Sheet: 150 Most Repeated Formulas From 10 Years PYQs
Below you will find the expanded, detailed list, written to enhance understanding and retention.
1. Units, Dimensions & Error Analysis
These are highly scoring because:
- They are formula-based
- Questions are easy
- Patterns are predictable
Most repeated formulas:
- Dimensional formula of velocity, acceleration, force, energy, power, etc.
- Error in sum/subtraction:
Δy = Δa + Δb - Error in multiplication/division:
Δy/y = Δa/a + Δb/b - Error in powers:
Δy/y = n (Δa/a) - Significant figure rules
- Error in mean value
PYQs heavily test multiplicative errors and power-dependent errors.
2. Kinematics
