Candidates should be able to:
- recall a definition of SHM and understand the concepts of period and amplitude;
- use standard SHM formulae in the course of solving problems;
- set up the differential equation of motion in problems leading to SHM, recall and use appropriate forms of solution, and identify the period and amplitude of the motion;
- recognise situations where an exact equation of motion may be approximated by an SHM equation, carry out necessary approximations (e.g. small angle approximations or binomial approximations) and appreciate the conditions necessary for such approximations to be useful.
