A wide variety of problems in Physics can be described in terms of vector operators and differential equations. By the end of the module the student should be able to express common physical systems and relationships using the mathematical language of vectors and differential equations. Topics covered include scalar and vector triple products, description of motion in polar co-ordinates, scalar and vector fields in physics, gradient of a scalar field, divergence and curl of a vector field, vector calculus in cylindrical and spherical polar co-ordinates, eigenvalue problems, general order linear ordinary differential equations, simultaneous differential equations, partial differential equations.
The relevance of the above topics to the physical sciences is illustrated throughout with examples drawn from electrostatics, magnetism, gravitation, mechanics, plasma physics and fluid dynamics.
After taking this module students should:
Additional learning activities
Practice at problem-solving is an essential element of Mathematics learning. For this reason, this module combines Lectures with Workshop sessions, where you will get a sheet of questions which you should start attempting during the session itself. A member of staff will be there to help you should you encounter any difficulties with any of the questions. Your marks will constitute the 30% continuous assessment element of the module.
Scalar and vector products, highlighting the value of vector notation by application (and simplification) of some physical situations.
2D motion using (r,0) co-ordinate system. Scalar and vector fields tying in with existing knowledge of electrostatics, magnetism, gravitation and pressure along with methods of visualising these fields i.e. contour plots, vector arrow plots.
