NLM Numericals– 09 | Contact Force between Two Blocks on Rough Surface | Class 11 | JEE & NEET

In this NLM Numericals series, we solve selected problems based on **Two-Block and Three-Block Systems on a Horizontal Surface**. These problems cover both **smooth and rough horizontal surfaces**, where two or three blocks are in contact and external forces are applied to the system. Concepts Covered: • Acceleration of a system of connected/in-contact blocks • Normal Reaction and Contact Force between blocks • Two-block problems on a horizontal surface • Three-block problems on a horizontal surface • Smooth horizontal surface • Rough horizontal surface with friction • Distribution of applied force among blocks • Finding individual contact forces/reactions • Free Body Diagrams (FBDs) and application of Newton’s Laws of Motion These are **focused numerical problems from the NLM chapter**, designed to help Class 11 students build a strong understanding of Newton’s Laws rather than relying on memorized formulas. 🎯 Useful for: *Class 11 Physics | JEE Main | JEE Advanced | NEET* This video is part of the *NLM Numericals* series of Physics EduMedia, where important Newton’s Laws of Motion problems are solved step-by-step. 📌 *Chapter: Newton’s Laws of Motion (NLM)* 📌 *Topic: Two & Three Blocks in Contact – Horizontal Surface* If you find the problem useful, try solving it yourself before watching the complete solution. #NewtonLawsOfMotion #NLM #Physics #JEE #NEET #Class11Physics #ContactForce #NormalReaction
