Restitution ka Concept JEE ke Liye – Coefficient of Restitution Explained in Easy Hindi
🎬 Restitution ka Concept – Ekdum Easy! "Jab do objects takraate hain, to unke bounce back karne ki ability ko hi bolte hain Coefficient of Restitution!" ⚡ What is Coefficient of Restitution (e)? Formula: e = (Relative speed after collision) / (Relative speed before collision) It tells us how “bouncy” a collision is. Simple! 🧠 Important Points to Remember: 0 < e < 1 → Partially Elastic Collision (thoda bounce, thoda energy loss) e = 1 → Perfectly Elastic Collision (poora bounce, no energy loss) e = 0 → Perfectly Inelastic Collision (no bounce, objects stick together) 🧪 Real-Life Example: Let’s say a ball hits the ground : If e = 0.8 → Ball bounce karegi, par speed thodi kam hogi If e = 0 → Ball bilkul waapas nahi aayegi (stick to ground) ❗ Memory Trick (Easy Yaad Karne Ke Liye): e = After / Before Numerator = After collision Denominator = Before collision Bas itna yaad rakho! 📢 Conclusion: "Bounce kitna hoga?...
