Module description

This module 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, multi-particle 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.

Main Topics:
1. Newton's laws of motion(single particles and systems of many particles).
2. The Lagrangian formalism.
3. Small oscillations and stability.
4. The motion of rigid bodies.
5. Hamiltonian formalism.

Module aims

The aim of the module is to develop an understanding of how Newton's laws of motion can be used to describe the motion of systems of particles and rigid bodies, and how the Lagrangian and Hamiltonian approaches allow use of more general coordinates systems to simplify treatments of many interesting problems in physics and sciences.

Module learning outcomes

On completion of the module, students should be able to:
* model simple mechanical systems, usingNewton's laws of motion and Lagrange's equations;
* analyse the dynamics of systems near equilibrium (small oscillations and stability);
* relate the Hamiltonian and Lagrangian approaches;
* recognise and make use of conserved quantities;
* find the Euler-Lagrange equations associated with simple problems;
* have an understanding of Liouville's theorem, PoincarĂ©'s recurrence theorem, poisson brackets and canonical transformations.

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. 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.
