The aim of this module is to give the learner an introduction in physical and measurement science with a particular emphasis on rotational, vibrational, and oscillatory dynamics. Additional areas of basic material science and light and optics are included with a focus on industrial and engineering applications. An emphasis on applied problems and lab work will give the learner a practical knowledge of the application of both theory and practical methods.
