**Description**

The student will learn the basic laws of Physics pertaining to Engineering including defining the standard units of measurement, forces, and the properties used in modern day engineering. The student will be able to explain experimentation, how heat is transferred, radioactivity, thermal expansion, efficiency calculations, fluid pressure, and some wave theory.

This module is taught by a number of lecturers and includes many real life situations where the topics covered are used.

### Learning Outcomes

*On completion of this module the learner will/should be able to;*

**1.**

Be able to solve various exercises involving physics, such as heat transfer and thermal expansion using and manipulating the correct units of measurement

**2.**

Be able to determine the efficiency of various simple machines, explain their operation and determine their mechanical advantage (force ratio) and velocity ratio (movement ratio)

**3.**

Be able to explain properties such as temperature and pressure and be able to use the gas laws to determine values for properties which undergo change.

**4.**

Be able to explain wave propagation, sound and light and be able to explain simple reflection, refraction, diffration, and interference of waves, plus use the doppler effect to solve for changes in perceived frequencies.

**5.**

Be able to explain reflection, and refraction of light and show how images are formed in mirrors.

### Teaching and Learning Strategies

This module is designed to give the students theoretical knowledge of physics which is backed up by a quiz each week to ensure the students engage with the topic. There will also be laboratory practicals, where the students will carry out experiments, record results, produce a report which will make conclusions and recommendations.

### Module Assessment Strategies

This course is designed to be a mixture of continuous assessment, practical experimentation, and terminal examinations. There is a quiz each week on IT Sligo's learning management software, plus every week the students attend for a practical experiment. There is also the possibility to have minor assessments during the semester.

A terminal examination will be held at the end of the semester and accounts 70% of the overall mark.

### Repeat Assessments

Repeat assessment will be by way of sitting another examination on the subject. Alternatively, at the discretion of the lecturer, assignments covering the deficient areas of the course may be set.
