Friction L-4: Rolling Friction, Spring Force & Conceptual Numericals

Welcome to Friction, Lecture 4! 🛑 We are expanding our mechanics toolkit today by exploring Rolling Friction and the fundamentals of Spring Force ($F = -kx$). In this session, we analyze the microscopic causes of rolling resistance, dive into the mechanics of elastic springs, and solve high-yield numerical questions that combine these forces seamlessly.
