Scalar-Based:

Working with energy (scalars) is often much easier than tracking 3D force vectors. Common Problems You’ll Encounter Generalized Coordinate: Let (x) be the downward displacement

1. Generalized Coordinate: Let (x) be the downward displacement of (m_1). By string constraint, (m_2) moves up by (x). The pulley rotates by (\theta = x/R).
2. Kinetic Energy:
