Description

This module uses lectures and guided self-study to develop students' understanding of Newtonian classical mechanics and special relativity. Although some of the concepts will be familiar from A-level, vector notation will be used throughout. Particular emphasis is placed on the precise and consistant application of the laws and methods.

Module Aims

Our interest in mechanics arises from its general applicability to a vast number of familiar phenomena. This module provides meaningful and easily visualizable problems which allow development of the skills of problem solving, required in all the fields of physics. It provides the necessary background to later modules that will apply the principles of mechanics to the solution of more complex problems.

Intended Learning Outcomes (ILOs)

A student who has passed this module should be able to:

• Module Specific Skills and Knowledge:
  1. recognise and describe the forces that are relevant in a given mechanics situation;
  2. describe the origin of and relationship between these forces, and to describe what their consequences will be;
  3. solve a range of mechanics problems as defined by the syllabus below, and by examples given in the lectures and worksheets;
• Discipline Specific Skills and Knowledge:
  4. apply general problem-solving strategies not only to mechanics but also to the solution of other physics problems;
  5. demonstrate a knowledge of mechanics that will be applicable in a range of other physics modules;
  6. use vector notation consistently and correctly as an integral part of solving problems;
  7. use symbols that represent the numerical value and units of the physical quantities, and manipulate/evaluate expressions involving such symbols in a precise and consistent manner;
• Personal and Key Transferable / Employment Skills and Knowledge:
  8. undertake guided self-study successfully;
  9. develop appropriate time-management strategies and meet deadlines for completion of work.
