🔴 Class 11 Physics | Oscillations Lecture 6 | Damped & Forced Oscillations + Resonance | NEET 2026

Welcome to Lecture 6 of the Oscillations chapter – the most crucial and high-scoring part for NEET 2026 aspirants!
In this lecture, we deep dive into Damped Oscillations, Forced Oscillations, and Resonance with detailed explanations, graphs, equations, and tons of NEET previous year questions.
✓ Topics Covered in Lecture 5:

Periodic vs Oscillatory Motion
Simple Harmonic Motion (SHM): Equation, Phase, Displacement x = A sin(ωt + φ)
Velocity v = ω√(A² - x²), Acceleration a = -ω²x
