This introductory unit provides students with basic knowledge and skills in mechanics, optics, electromagnetism and electronics. This knowledge will be developed in later units. Emphasis is placed on the practical applications of the physical principles embodied in these fields and the theoretical basis is developed, only to the extent that it is sufficient for the student to comprehend the practical application.

1 Attendance at residential school is compulsory for this unit. To
be awarded a pass grade students must normally gain at least 60%
of the possible marks for the reports of the practical work.
2 The final examination id sn open book type.
3 Because it is mormal practice to release model answers promptly
after the due date the penalty for late submission of any
assessment is normally the loss of all marks for the assessment.
4 Students gaining 60% or more of the total marks for the unit,
will be automatically awarded a pass grade. The cut off marks
for grades of C, B, A and HD will be determined by the examiner
and moderator following an inspection of a histogram of the marks
gained by students. The results of students gaining less than
60% will be considered individually by the examiner and
moderator. They may then recommend a grade of C, or IS, or IM,
or ISM, or F, depending on the individual's performance in the
various assessments.
