Physics BSc Hons - 2020 Entry

Course Structure

Lancaster University offers a range of programmes, some of which follow a structured study programme, and others which offer the chance for you to devise a more flexible programme to complement your main specialism. We divide academic study into two sections - Part 1 (Year 1) and Part 2 (Year 2, 3 and sometimes 4). For most programmes Part 1 requires you to study 120 credits spread over at least three modules which, depending upon your programme, will be drawn from one, two or three different academic subjects. A higher degree of specialisation then develops in subsequent years. For more information about our teaching methods at Lancaster please visit our Teaching and Learning section.

The following courses do not offer modules outside of the subject area due to the structured nature of the programmes: Architecture, Law, Physics, Engineering, Medicine, Sports and Exercise Science, Biochemistry, Biology, Biomedicine and Biomedical Science.

Information contained on the website with respect to modules is correct at the time of publication, and the University will make every reasonable effort to offer modules as advertised. In some cases changes may be necessary and may result in some combinations being unavailable, for example as a result of student feedback, timetabling, Professional Statutory and Regulatory Bodies' (PSRB) requirements, staff changes and new research.

Year 1

Core

• Basic Physics Skills / Communication Skills

  This module is made up of both lectures and practical sessions, aiming to developing your communication skills through the preparation and delivery of a verbal presentation and written scientific report.

  The lectures will allow you to consider systematic approaches to problem solving including good methods in working and presenting answers, and in selecting and testing maths expressions in modelling.

  In Classical Mechanics students will apply the ideas of fundamental Newtonian mechanics to real large scale systems such as rotating bodies, planetary systems and classical fluids.

  The focus is on gravitation and its central importance in determining the large scale behaviour of the Universe. Concepts such as inertial and gravitational mass, Mach's principle, black holes and even dark matter will be explored.
