• Owning School: Mathematics, Statistics and Physics
• Teaching Location: Newcastle City Campus
##### Semesters
 Semester 1 Credit Value: 10 Semester 2 Credit Value: 10 ECTS Credits: 10

#### Aims

To present the dynamics of simple and damped harmonic oscillators and to give examples of systems exhibiting this behaviour. To present the impact of a driving force on this motion and the phenomenon and description of resonance.

To present techniques needed for analysis DC and AC circuits. To impart an appreciation of the analogy between AC circuits analysis and mechanical oscillations.

To present an introduction to the subject of coupled oscillations, with an introduction to normal mode analysis.

To present an introduction to wave propagation and an introduction to the wave equation. To introduce phase and group velocities and the Doppler effect.

To present a study of the transmission and reflection of waves at interfaces.

To introduce concepts of states of matter with a focus on solid state materials to act as a foundation for later course.

To introduce phase diagrams and discuss phase transitions.

To give some understanding of some thermal properties of matter.

#### Outline Of Syllabus

Harmonic motion: dynamics and mechanical origin.
Damping, quantification of damping.
Forced harmonic motion. Resonance
Superposition of SHM: beats.
Elementary analysis of DC and AC electrical circuits. Analog of mechanical system.
Coupled oscillations and normal modes. Physical concept of superposing normal modes and Fourier series.

Wave motion and the wave equation in one dimension. D’Alembert’s solution of the wave equation.
Waves on strings, sound waves and electromagnetic waves.

Reflection and transmission at interfaces.
The Doppler effect
Bonds between atoms: ionic bonds, metallic bonds, covalent bonds, molecular bonds, comparative strength of the bonds.
Ideal Gases: kinetic theory, specific heat of gases, mean free path.
Gas-liquid phase transitions: modifications to the ideal gas equation, continuous and discontinuous transitions between liquids and gases.
Liquids: the role of intermolecular forces in understanding surface tension and viscosity.
Order-disorder transitions: amorphous solids, liquid crystals.
Solids: the unit cell, crystal planes, methods of determining crystal structures

#### Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

##### Teaching Rationale And Relationship

Non-synchronous online materials are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on assessed work. Present-in-person and synchronous online sessions are used to help develop the students’ abilities at applying the theory to solving problems and to identify and resolve specific queries raised by students, and to allow students to receive individual feedback on marked work. Students who cannot attend a present-in-person session will be provided with an alternative activity allowing them to access the learning outcomes of that session. In addition, office hours/discussion board activity will provide an opportunity for more direct contact between individual students and the lecturer: a typical student might spend a total of one or two hours over the course of the module, either individually or as part of a group.
Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

#### Assessment Methods

There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

The format of resits will be determined by the Board of Examiners

##### Assessment Rationale And Relationship

The course assessments allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these assessments have a secondary formative purpose as well as their primary summative purpose.
