Learning unit contents

The Lagrangian formulation of mechanics is intimately connected to the introduction of generalized coordinates which are used to describe the motion of a system of particles (including the solids) by elimination of possible constraints restricting their motions. We first introduce the Lagrange's equations and apply this formalism to several different problems (e.g. study of the symmetric top, known as the Lagrange-Poisson problem). Then, we consider the symmetries of a problem and determine the associated conserved quantities. The Hamilton variational principle is also discussed.

Learning outcomes of the learning unit

At the end of the course, the students will have understood the physical concepts and principles of lagrangian mechanics. They will also be able to solve problems related to this subject.

Prerequisite knowledge and skills

It is assumed that the course Analytical Mechanics I is familiar to the students.

Planned learning activities and teaching methods

The theoretical part of the course is presented as lectures. Practical work sessions are also devoted to solving problems and making exercices.

Mode of delivery (face to face, distance learning, hybrid learning)
