bullet

Useful conversion factors and constants   You may find this list of conversion factors useful for various problems this unit and year
bulletUnit Objectives:  This is a summary of the syllabus statements that are detailed on the topic outline.
bulletUnderstand the concept of "Orders of Magnitude" and how to use this in estimations
bulletDemonstrate proficiency in the proper use of fundamental and derived metric (SI) units; demonstrate proficiency in performing conversions between metric units
bulletUnderstand concepts related to uncertainty and error in experimental measurements, and appropriately carry these errors through calculations
bulletDemonstrate proficiency at interpreting and analyzing information on graphs, including being able to manipulate equations until a linear relationship can be plotted and being able to represent/interpret uncertainties in graphs
bulletUnderstand concepts and calculations related to both vector and scalar quantities
