Experimental physics is introduced, providing practice in the basic skills in scientific measurement and a background to the theoretical concepts taught in the module.
Treatment of experimental errors.
At the end of this module students will be able to demonstrate knowledge and understanding of the elementary physics associated with:
• electrostatics and the energy contained in capacitors;
• electric circuit elements and their combination;
• magnetism and its effect on current carrying conductors in a magnetic field;
• temperature and its measurement,
• heat transfer,
• the kinetic theory of gases
• periodic motion,
• wave motion,
• interference of waves.
At the end of this module students will be able to communicate effectively the scientific content of the module contributes to the written communications skills of the student. The scientific problem solving element enhances general problem solving skills and initiative.

The subject material is highly knowledge based and requires lectures to disseminate the material. The problems-solving classes enhance knowledge and consolidate the students’ understanding of the material.
The format of resits will be determined by the Board of Examiners
The module is intended to provide a factual knowledge base. A formal written examination is most appropriate in this case. The in-course assessment encourages a consistent approach to learning.
Resit examination is the same. Resit of laboratory work by special exercise.
Special arrangements may be required for Study Abroad Students.
