Module overview

The module provides a coherent development of the methods of analytical classical mechanics and their applications for students at FHEQ 5 level. The module develops both the necessary formal background and provides practical experience and examples of several applications that enable the derivation of the equations of motion for a more diverse set of physical systems. The module incorporates an existing computational modelling experience that will support the taught material through the numerical implementation and study of a particular physical system.

Module aims

review the vector-based mechanics of Newton and disuss the role of conservation laws

provide a coherent development, via the Minimum Energy, Virtual Work and D'Alembert Principles, of the physical basis and application of the Lagrangian and Hamiltonian formulations of classical dynamical systems and their solution.

by the use of examples and selected applications, develop a familarity and a working knowledge of the appropriate choice of generalised coordinates and of constructing the Lagrangian and Hamitonian equations of motion for e.g. linear and rotational motion.

via the computational modelling component of the module, give a practical experience of the numerical implementation and the solution of a chosen dynamical system.

Module content

Indicative content includes:

Introduction and review: Vector nature of Newton’s Laws, the motions of sytems of interacting particles, conservation laws, Energy and the Minimum Energy Principle, degrees of freedom and constraints, Principle of Virtual Work and D’Alembert’s Principle (with their applications to simple mechanical systems).
Lagrangian Mechanics: Generalised co-ordinates, velocities and forces, and the derivation of Lagrange’s equation. Applications of the Lagrange equation to projectile motion, pendula, motion and orbital properties in a central potential, motion in a rotating frame and rotational motion, oscillatory systems and normal modes analysis.
Hamiltonian Mechanics: Generalised momenta, derivation of Hamilton’s equations of motion. Revisit of several of the applications in the Hamiltonian formulation.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Support the practical, problem solving and computational applications of the methods by the provision of a coherent series of lectures that develop the physical basis and derive the formal methods that underpin the (differential) equations of motion of Lagrange and Hamilton.


The learning and teaching methods include:

Lectures and tutorial periods (30 hours) to introduce the mathematical and formal methods and to practice the application of these methods to model systems in a supported tutorial environment.

Computational laboratory sessions (20 hours) for the conduct of an individual project that is designed to reinforce to major concepts of the lecture course.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

Familiarity and understanding, via unseen problems, of the content of the course materials and the ability to apply these in a new and unrehearsed situation. To apply computational methods and expertise taught in other courses to develop a methodology and computer code to solve and analyse a physical dynamical system of their choosing, with emphasis on the accuracy and the physical results of the model constructed.


Thus, the summative assessment for this module consists of:

·         Closed book examination (answer 2 questions from 3) covering the syllabus of the course as outlined above (70%)

·         Computational modelling project (30%), comprising an assessed interim report (7.5%) and an assessed final report (22.5%).


Formative assessment

Formative feedback on the lecture-based material will be provided by the provision of a marked, mid-semester take-home exercise with questions of the form expected in examinations papers.



Weekly interactive meetings take place in the computational laboratories with feedback on methods and the science. Tutorial support and feedback on progress on examples sheets will be provided as part of the timetable.
