Objectives

The aim of this module is to provide students with the core concepts and techniques in Physics within the areas of Waves, Mechanics, Electricity & Magnetism, Thermal Physics and Modern Physics . It will develop their knowledge and understanding of key physics concepts and their applications across science and engineering disciplines.

Learning outcomes
At the end of this module students should be able to:
- Describe the properties of waves, and how waves interfere to produce standing waves and interference patterns.
- Determine the path of a light ray through different media.
- Apply Newton's laws of motion to systems in equilibrium and rigid bodies moving under the action of simple systems of forces.
- Use vectors to solve problems in mechanics.
- Articulate the concepts of momentum, work, energy and power, and how these are related.
- Apply the basic principles of electricity and electric fields, and apply these to solve problems involving simple circuits.
- Articulate the principles of electromagnetic induction and its applications in the modern world.
- Describe how heat is transported through different media and articulate the effect of changes in temperature in solids, liquids and gases.
- Describe the structure of the atom and how this relates to radioactive decay.

Skills outcomes
- The ability to model a physical problem.
- The ability to solve physical problems using mathematics.
- The ability to use the knowledge gained in this module in new situations and to solve related problems.
- To gain practical experimental skills in physics.
- The ability to be able to describe, explain and interpret results in physics terms and be able to apply mathematical methods to analyse results.
