Circular Motion Problem: Minimum Velocity to Maintain Contact | Physics | phq1001

🎯 In this video, we solve a classic circular motion problem often seen in JEE Main, JEE Advanced, NEET, and Physics Olympiads: "What is the velocity of the ball at point B, where it barely makes contact with the surface?" (Assume frictionless conditions.) We break it down step by step using clear slides, analyzing forces at a general position and then focusing on the critical point B (top of the loop)—where the normal force becomes zero. You’ll see how to apply Newton’s laws and centripetal force concepts to find the minimum velocity required. This is a must-know concept for vertical circular motion—perfect for building strong fundamentals in mechanics! 📚 Key Concepts Covered: Centripetal force in vertical circular motion Role of normal force and gravity Condition for "barely maintaining contact" (N = 0) Derivation of minimum velocity at the top of a loop 🔔 Subscribe to ‪@Learn-with-Slides‬ for more Physics, Chemistry, and Maths problem-solving videos—explained clearly, one slide at a time! 👉 New videos every week for JEE, NEET, Olympiad & board exam prep. 💬 Try it yourself! and solve before watching the solution. 👇 Comment your answer or ask doubts below! #Physics #CircularMotion #JEEPhysics #NEETPrep #Mechanics #LearnWithSlides #ProblemSolving #STEM
