After taking this module students should be able to:
make use of the fact that energy can be transferred or converted from one form to another
relate the energy transferred to an object by the force exerted on the body and the distance it moves
state the principle of the conservation of energy and apply it to a variety of energy conversions
recognise that there are different units of energy
recall the formulae for kinetic energy and gravitational potential energy of an object
recall the basic atomic and nuclear structure of atoms
describe the basic science of radioactivity, nuclear fission and nuclear fusion
describe the nature of heat energy and the difference between heat energy and temperature
describe the different ways in which heat energy is transferred between two bodies
state the first and second Laws of Thermodynamics and their application to the efficiency of heat engines and refrigerators
recognise the function of the basic components of a conventional power station, whether driven by coal, oil or nuclear power
describe the mode of operation of hydroelectric, tidal and wind turbines
be able to make a balanced assessment of the advantages and disadvantages of different methods of generating electricity.
describe how pollutants can build up in the atmosphere near the ground
describe the basic processes underlying the acid rain and global warming problems.
Energy is a vital resource in our society. Its use and misuse has implications for the environment, and these issues have assumed dramatic proportions recently. This module discusses the fundamental physics behind energy resources, both conventional and alternative, in order to provide a balanced view of environmental implications. In this approach, the interdisciplinary nature of the subject is evident, and the module gives special emphasis to changes in the atmosphere - including acid rain and the greenhouse effect. The module is suitable for undergraduates of any discipline.
