Access Index ### Course description and aims

Analytical dynamics is important in mechanical, control, and systems engineering. Newton’s equations of motion can take complicated form in many-body systems or in systems with constraints. In analytical dynamics, simple and general description of the system dynamics is developed, which is invariant under coordinate transformations. Relations between the symmetries of the system and conserved quantities such as the energy and angular momentum are clarified. In the Hamiltonian description, the system dynamics is described as trajectories in the phase space spanned by the position and momentum of the system, which is further generalized to the dynamical systems theory. The following topics will be covered in the course: Lagrange’s equations, generalized coordinates, symmetries and conservation laws, variational methods, Hamilton’s equations, phase space and Liouville’s theorem, oscillations, rotation of rigid bodies.

### Student learning outcomes

The aim of this course is to understand the Lagrangian and Hamiltonian formalisms of the laws of motion, which are generalizations of Newton’s equations of motion, to learn the related mathematical methods such as coordinate transformations and variational methods, and to apply the formalisms of analytical dynamics to actual problems.

### Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
