Comprehensive formula sheet covering Mechanics, Electrodynamics, Optics, and Modern Physics. Includes memory tricks, derivations, and application examples.

Mechanics — Foundation of Physics

Equations of motion: v = u + at; s = ut + ½at²; v² = u² + 2as
Newton's Second Law: F = ma; Work = Fd cos θ
Conservation of energy: KE + PE = constant
Gravitation: F = Gm₁m₂/r²; g = GM/R²

Electrodynamics and Circuits

Ohm's Law: V = IR; Power: P = VI = I²R
Kirchhoff's Current and Voltage Laws
Faraday's Law of Induction: ε = −dΦ/dt
Capacitance: C = Q/V; Energy stored = ½CV²

Optics and Modern Physics

Mirror formula: 1/f = 1/v + 1/u; Lens formula: 1/f = 1/v − 1/u
Snell's Law: n₁sinθ₁ = n₂sinθ₂
Photoelectric effect: KE_max = hf − φ
de Broglie wavelength: λ = h/mv

Memorizing Formulas Effectively

Group related formulas by topic — do not memorize in isolation
Understand the derivation so you can reconstruct the formula
Use dimensional analysis to verify formula correctness
Practice numericals using each formula immediately after learning
