**Description**

This module has been designed to introduce the student to the basic principles of engineering science theory. The student will learn about mechanics, transfer of heat, fluid pressure, radiation and motion. He/she will become familiar with the operation of basic laboratory equipment, the gathering and analysis of experimental data and the safety concerns related to experimental work.

### Learning Outcomes

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

**1.**

Define the concepts used in kinematics, heat transfer and fluid pressure and use the associated concepts and laws to calculate unknown quantities

**2.**

Explain why radioactivity occurs and outline the properties of alpha, beta, and gamma radiation. Explain nuclear fusion and nuclear fission. Determine the binding energy of an atom and the end product of various radioactive decay mechanisms.

**3.**

Explain the difference between sound waves and light waves. Represent reflection using diagrams and explain refraction. Describe what happens when a noise is produced and explain the Doppler Effect. Calculate the sound frequency when the source is approaching and moving away from the observer and determine the sound level when a number of sound sources are present.

**4.**

Define voltage, current, resistance and power. Calculate the resistance of resistors in parallel or in series.

**5.**

Use standard laboratory equipment and perform as a team member in the execution, compilation, analysis and interpretation of laboratory experiments

**6.**

Compile and report, in both written and oral form, using word and excel, the results and conclusions of laboratory work
