Damped & Forced Oscillations | Complete Concept + Numerical Practice | TGT PGT LT Physics | JRS Academy VK Sir

📘 Description:

Welcome to today’s Physics class with VK Sir at JRS Academy!
In this session, we cover two of the most important concepts from Oscillatory Motion — Damped Oscillations and Forced Oscillations. These topics form the foundation of real-life oscillatory systems and are frequently asked in TGT, PGT, LT, B.Ed, and competitive Physics exams.

You will learn how oscillations behave under damping, how external periodic forces change the motion, and how resonance plays a crucial role in physics and engineering.
