NCERT Class 11 Physics | Oscillations Ex 14.7 | Phase in SHM Explained | JEE NEET

This video is a detailed, concept-based solution of 📘 NCERT Class 11 Physics – Oscillations 📌 Exercise Question 14.7 Instead of jumping directly to the answer, I follow a PHYSICS-FIRST approach: ✔ Understand the question deeply ✔ Build physical meaning of phase in SHM ✔ Connect equations with real motion ✔ Then solve the NCERT question correctly 🔍 What this NCERT question actually tests: • Do you understand what PHASE physically represents? • Do you know that amplitude and phase are NOT arbitrary? • Can you relate initial position and velocity to future motion? • Do you understand why sine and cosine describe the SAME motion? 📌 Key concepts explained: • Physical meaning of phase in SHM • Why velocity and acceleration are locked to phase • Why sine vs cosine does NOT change motion • How changing sine ↔ cosine only shifts time origin • How NCERT frames conceptual questions for JEE & NEET Formula discussed: x(t) = A cos(ωt + φ) Once phase is known: ✔ Direction of velocity is fixed ✔ Speed magnitude is fixed ✔ Direction of acceleration is fixed This video is useful for: ✅ CBSE Class 11 students ✅ NCERT-based learning ✅ JEE & NEET aspirants ✅ Students struggling with SHM concepts 👉 Watch till the end to see how NCERT expects you to THINK, not just calculate. 🔔 Subscribe to "Lets Love Physics" for deep, exam-oriented Physics explanations.
