Lagrange's Equations Introduction - Generalized Coordinates, Constraints, Degrees of Freedom

Explore the energy-based Lagrangian approach to mechanics in this comprehensive lecture on analytical dynamics. Learn about generalized coordinates, constraints, and degrees of freedom as foundational topics. Delve into holonomic and nonholonomic constraints, with a focus on rolling without slipping. Examine various examples to reinforce understanding, and discover the surprising dynamics of the "shopping cart instability". Gain insights into efficiently deriving equations of motion for mechanical systems using variables that avoid calculating unnecessary reaction forces.
