### Objectives

- To introduce particular physics topics and relate them to the Engineering disciplines;
- To further develop an understanding of mechanics and waves as aspects of physics which are relevant to Engineering;
- To undertake simple calculations using relevant laws and equations;
- To solve basic and more complex real-world problems about applications of this topic;
- To develop good and sensible laboratory practice and the reporting of experiments;
- To build confidence in presenting physics work in a scientific style in English.

Learning outcomes
- An understanding of aspects of physics which are most relevant to Engineering; in particular mechanics and waves;
- Ability to understand physics problems presented in English;
- Ability to undertake physics laboratory experiments;
- Ability to present physics work in English.

### Teaching methods

 Delivery type Number Length hours Student hours Example Class 16 1.00 16.00 Laboratory 2 3.00 6.00 Lecture 32 1.00 32.00 Independent online learning hours 32.00 Private study hours 64.00 Total Contact hours 54.00 Total hours (100hr per 10 credits) 150.00

### Private study

Independent Online Learning activities will include reviewing lecture notes and other material on the VLE. Typically recommended 2 hrs reviewing online material per teaching week.

Private study tasks relate to the content of the course including background reading such as text books and examples, and also the preparation of any assessed pieces of work including laboratory work.

Please note: all delivery types and number of hours are subject to variation, depending on immediate delivery needs. An 'hour' refers to one session in the timetable which is approximately 45 minutes long.

### Opportunities for Formative Feedback

Question sheets and marked work. Feedback from smaller examples classes and laboratory sessions. End of semester 1 exam.

### Methods of assessment

Coursework
 Assessment type Notes % of formal assessment Practical Report Laboratory Report 2 10.00 Practical Report Laboratory Report 1 10.00 In-course Assessment 1 Hour In-Class Test 25.00 Total percentage (Assessment Coursework) 45.00

Normally resits will be assessed by the same methodology as the first attempt, unless otherwise stated

Exams
 Exam type Exam duration % of formal assessment Standard exam (closed essays, MCQs etc) 2 hr 00 mins 55.00 Total percentage (Assessment Exams) 55.00

The resit will consist of one 2 hour exam which will assess all learning outcomes of the module.
