Generalized coordinates, generalized velocity, generalized momentum, and equations of motion form the backbone of Lagrangian mechanics and are repeatedly asked in NET, GATE, JEST, and JAM examinations.
In this lecture, these concepts are developed from first principles, avoiding rote formulas and focusing on physical interpretation and problem-solving clarity.
🔹 What you will learn in this video:
Why are generalized coordinates introduced, and how do they simplify constrained systems
Definition and meaning of generalized velocity
Concept of generalized momentum and its relation to the Lagrangian
Derivation and interpretation of Lagrange’s equations of motion
Common mistakes students make in exams (and how to avoid them)
🔹 Who should watch this:
CSIR-NET (Physical Sciences) aspirants
GATE Physics
JEST
IIT-JAM Physics
MSc / PhD students studying Classical Mechanics
This lecture is designed to help you think like an examiner, not just memorize equations.
If you struggle to connect constraints, coordinates, and equations of motion video will fix that gap.
