Physics180 marks (25% of NEET)

NEET Physics chapter weightage.

NEET Physics is 45 questions × 4 marks = 180 marks. Concept-driven, formula-heavy, and the most score-pulling subject for students aiming above 600.

Physics is the subject where most NEET 600+ scorers are made or broken. Unlike Biology (which rewards memorization) and Chemistry (which is half-recall), Physics requires problem-solving fluency under time pressure. The syllabus is split roughly equally between Class 11 (Mechanics, Thermodynamics, Waves) and Class 12 (Electromagnetism, Optics, Modern Physics). Most students need to spend ~30% of their study time on Physics — even though it's only 25% of marks.

Based on past-paper analysis 2018–2025

Mechanics

9–11 questions per year (~25% of Physics)

Mechanics is the largest single chapter group in NEET Physics, covering kinematics, Newton's laws, work-energy, rotational motion, and gravitation.

Thermodynamics

3–4 questions per year (~10% of Physics)

Thermodynamics covers laws of thermodynamics, heat engines, Carnot cycle, and kinetic theory of gases — usually 3-4 questions but high-yield because the formulas are limited.

Practice readyOpen chapter →

Optics

3–5 questions per year

Ray optics + wave optics. Lens/mirror formulas, Young's double slit, polarization. Dependable for ~4 questions every year.

Practice readyOpen chapter →

Electrostatics

3–5 questions per year

Coulomb's law, electric field, potential, capacitance, dielectrics. Heavy on numerical work and Gauss's law applications.

Practice readyOpen chapter →

Modern Physics

5–6 questions per year

Photoelectric effect, atomic models, nuclei, radioactive decay, semiconductors. Highly scoring because the formulas are limited and recur every year.

Practice readyOpen chapter →

Current Electricity

3–4 questions per year

Ohm's law, Kirchhoff's laws, Wheatstone bridge, resistivity, drift velocity, EMF, internal resistance.

Practice readyOpen chapter →

Waves and Sound

2–3 questions per year

Transverse and longitudinal waves, superposition, beats, Doppler effect, sound in pipes and strings.

FAQ

How many questions of Physics are in NEET?▾
NEET Physics has 45 questions worth 180 marks total (25% of NEET's 720). Each question follows the +4 correct, −1 incorrect marking scheme.
Which is the most important chapter in NEET Physics?▾
Based on past-paper analysis from 2018–2025, the highest-weightage chapter in NEET Physics is Mechanics (9–11 questions per year (~25% of Physics)). Mastering it covers a substantial portion of the section.
Is NCERT enough for NEET Physics?▾
NCERT is the foundation for NEET Physics but most students need at least one additional problem book for practice variety, especially for Physics (HC Verma, DC Pandey) or Chemistry Physical (NCERT + Atkins/JD Lee for inorganic).
