Back to
"General Physics"



 Unit Objectives:
 to understand the fundamental and derived
units of the metric system 
 to master metric unit conversions using the
factorlabel method and dimensional (unit) analysis 
 to understand experimental errors:
 to distinguish between random and systematic
errors 
 to understand the effect random and
systematic errors on experimental results 
 to understand how to reduce the effects of
errors on experimental results 
 to distinguish between experimental errors
and mistakes (i.e. computational mistakes, transferring incorrect raw
data to analysis, etc.) 

 to distinguish between precision and accuracy
of a set of data 
 to understand significant figures:
 to understand what is meant by the precision
of a tool 
 to determine an appropriate precision in a
calculated answer 

 To demonstrate mastery at the skill of proper
measuring and recording of experimental data
