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!
