Motion Graphs 😳 30 Sec में समझो!
(Alt) Distance-Time & Velocity-Time Graphs आसान तरीके से 🔥
Motion graphs अब easy 💥

👉 Distance-Time Graph → speed दिखाता है
👉 Velocity-Time Graph → acceleration दिखाता है

📌 Straight line = uniform motion
📌 Curve = non-uniform motion 😳

Graphs समझ गए → numericals easy 💯
