Information about fees and unit costs

Professionals in the applied sciences require an understanding of the processes of making and recording measurements and an understanding of the physical principles that govern the behaviour of both the physical parameters being measured and the instrument being used to make the measurement. The aim of this unit is to introduce you to the processes of making measurements and estimating, processing and interpreting the uncertainties involved with these measurements. To enable you to understand the physical parameters being measured and also the limits of the measuring instrument; the physics of mechanics, heat, sound and light will be introduced and explained.

Rationale

Professionals in the applied sciences require an understanding of the processes of making and recording measurements and an understanding of the physical principles that govern the behaviour of both the physical parameters being measured and the instrument being used to make the measurement.

Aims

The aim of this unit is to introduce you to the processes of making measurements and estimating, processing and interpreting the uncertainties involved with these measurements.

To enable you to understand the physical parameters being measured and also the limits of the measuring instrument; the physics of mechanics, heat, sound and light will be introduced and explained.

Objectives

Specific Objectives:

On completion of this unit you should be able to:

1. Evaluate and interpret the precision of recorded measurements.
2. Understand and apply basic equations of one- and two-dimensional mechanical motion, including kinematic equations, Newton's laws of motion, and conservation of momentum and energy.
3. Identify and explain the physical principles of humidity, heat energy and transfer, both at a microscopic and a macroscopic level.
4. Understand and apply the principles associated with reflection, refraction and diffraction of light, including the use of these principles in some common optical instruments.
5. Understand and explain the transmission, detection and measurement of sound.

Generic Attributes:

On completion of this unit you will have developed a range of generic attributes including:

  • Ability to define and solve problems

  • Ability to retrieve and evaluate information

  • Ability to think critically and creatively

  • Value truth, accuracy and honesty

  • Ability to work both independently and collaboratively
  • Content

    In this unit you will study some of the major themes in Physics; Mechanics, Heat, Light and Sound. The specific topics will include:

  • Introduction: Experimental techniques; uncertainties and error analysis

  • Mechanics: Dimension analysis; kinematics and dynamics; circular motion and gravitation; work and energy; rotational motion

  • Heat: Temperature; heat capacity; latent heat; heat transfer; practical thermometers; humidity

  • Optics: Geometrical optics; mirrors and lenses; physical optics; the visible spectrum; diffraction; polarisation; optical instruments; fibre optics

  • Sound: Vibrations; wave motion; intensity; the ear; sound quality and spectra; Doppler effect
  • Approaches to Teaching and Learning

    In this unit you will attend a number of lectures and practicals to explain and demonstrate the content as described above. This integrated lecture-practical program will be reinforced by a specially designed series of practical exercises which will each require you to complete individual Pre-Practical Questionnaires before the day of the laboratory session. You will be required to undertake directed private study to supplement the lecture program.

    Assessment

    You will be required to undertake the following mix of formative and summative assessment.

    Note: You must pass each of the three assessment components to achieve a passing grade in this unit.Feedback will be provided throughout the semester. Additional feedback can be sought by contacting the Unit Coordinator.

    Academic Honesty

    Academic honesty means that you are expected to exhibit honesty and act responsibly when undertaking assessment. Any action or practice on your part which would defeat the purposes of assessment is regarded as academic dishonesty. The penalties for academic dishonesty are provided in the Student Rules.
