NDA Physics Notes

Sound is NDA Physics's lowest-HARD chapter — 35 PYQs across 2017–2026, almost entirely EASY and MODERATE.

Electricity and Magnetism is the single biggest chapter in NDA Physics — 97 PYQs across 2017–2026 and the bank's #1 HARD pool.

Light and Optics is the biggest and most diagram-heavy chapter in NDA Physics — 102 PYQs across 2017–2026, and the chapter where a single sign convention makes or breaks a numeric answer.

Laws of Motion is one of NDA Physics's most reliably-tested chapters — roughly 44 PYQs across 2018–2026, almost entirely EASY and MODERATE (only ~10% HARD).

Formula-rich and steady, and the HARD questions are nearly always calorimetry or gas-process algebra — grindable, as long as you keep your units straight.

Modern Physics is one of NDA Physics's most reliable scoring chapters — about 25 PYQs across 2017–2025, every single one EASY or MODERATE, with ZERO hard questions.

Kinematics and Motion is 27 past-year NDA questions across 2017–2026, a steady earner with about a quarter of them HARD.

Fluid Mechanics is the toughest chapter in NDA Physics — about 24 PYQs across 2017–2026 and the bank's highest HARD share (~30%).

Work, Energy and Power is a steady, formula-light scorer in NDA Physics — 26 PYQs across 2017–2026, almost all EASY and MODERATE with only a couple of HARD outliers.

Gravitation is 19 past-year NDA questions across 2017–2026, a compact, formula-driven earner.

Units, Measurement and Dimensions is NDA Physics's most reliable scoring chapter — about 14 PYQs across 2017–2025, and roughly three-quarters of them are EASY one-line recall.

Oscillations and Waves is 14 past-year NDA questions across 2017–2026, tested in two tightly linked movements.
