Intro

Generalised coordinates are very important part of Lagrangian Formulation because we work in a configuration space.

Generalised Coordinates

To solve any physical problem the knowledge of constraints and degrees of freedom is necessary.

Constraints and Degrees of Freedom

Hamilton principle is known as principle of least action. It is the base of Lagrangian Formulation.

Hamilton’s Principle

Variational principle means variation in least action is zero. On the basis of this fact we can derive lagrange equation of motion.

Variational Principle

Lagrangian Equation of Motion

Applications of Lagrangian Equations of Motion

This problem is taken from very famous book Landau and Lifstiz Classical Mecanics. It is very intersting problem.

Simple pendulum in Uniform gravitational Field.

Problem is from Book Landau and Lifstiz Classical Mechanics.

Pendulum with moving support.

Applications part 4, Spherical Pendulum in uniform gravitational field.

Hamilton Principle for non holonomic systems

Why Mr. Lagrangian is important? because it is scalar and in the form of energy difference it gives you equation  of motion.

Why Lagrangian

Application, Cylinder rolling down on inclined plane

No miracle is possible, until Noether theorem exist. Nature follows rule of conservations.

Conservation Theorem

With the help of cyclic coordinates we can find out the conserved quantities to the corresponding Lagrangian very easily.

Cyclic Coordinate

Conservation of linear momentum

Similarity between Newtons law and Lagrangian equation of motion

Newtons Law from Lagrangian equation

Gauge Function is very important for the study of Electromagnetic Theory and Particle Physics. This video gives you brief idea about this.
