Measurements and their errors

Measurements and their errors

1. Use of SI units and their prefixes

   • fundamental units
   • use of mass,length,time,quantity of matter,temperature ,electric current and their associated SI units
   • SI units derived
   • knowledge/use of SI prefixes,values and standard form

2. Limitation of Physical measurements

   • random and systematic errors
   • precision,repeatability,reproducibility,resolution and accuracy
   • uncertainty

3. Estimation of physical quantities

   • orders of magnitude
   • estimation of approx. values of physical quantities
