Module description

This course concerns the general description and analysis of the motion of systems of particles acted on by forces. Assuming a basic familiarity with Newton's laws of motion and their application in simple situations, the students will develop the advanced techniques necessary to study more complicated systems. The students will also consider the beautiful extensions of Newton's equations due to Lagrange and Hamilton, which allow for simplified treatments of many interesting problems and provide the foundation for the modern understanding of dynamics. The module also includes an introduction to the calculus of variations, which allows the solution of an important class of problems involving the optimisation of integral quantities.

Main Topics:
1. Kinematics and dynamics of particles and systems of particles.
2. Calculus of variations (Equations of Lagrange - first and second kind. Least action principle).
3. Lagrangian formalism: D'Alembert principle vs variational principle.
4. Oscillations.
5. Hamiltonian formalism. Canonical transformations. Noether theorem and symmetries.

Module aims

The aim of the course is to develop an understanding of how Newton's laws of motion can be used to describe the motion of systems of particles and solid bodies, and how the Lagrangian and Hamiltonian approaches allow use of more general coordinates systems, and how the calculus of variations can be used to solve simple continuous optimization problems.

Module learning outcomes

On completion of the course, students should be able to:
* model simple mechanical systems, using Lagrange's equations;
* analyse the dynamics of systems near equilibrium; find the normal modes of oscillation;
* relate the Hamiltonian and Lagrangian approaches;
* recognise and make use of conserved quantities;
* find the Euler-Lagrange equation associated with simple variational problems.

Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
