CONTENT Unit, System of units, SI system, Error analysis, Dimensions, Use of dimensional analysis, limitations of dimensional analysis OBJECTIVES ? To develop knowledge about different types of units and system of units. ? To develop understanding about error analysis and dimensional analysis. ? To apply the knowledge acquired in different problems. TEACHING AIDS ? Weights of different types ? scales, ? vernier calipers ? screw gauge ? measuring jar ACTIVITIES ? Discussion on different types of unit systems. ? Discussion on errors in experiments. ? Derivation error during addition, subtraction, multiplication, division. ? Derivation of expression of different physical quantities. TEACHING POINTS ? Anything that can be measured is called physical quantity. ? Units are standards agreed upon for the measurement of a physical quantity. ? Units are of two type 1) fundamental units 2) DERIVED UNITS ? Units that can not be expressed in terms of other units are called fundamental units. Eg metre, kilogram, second ? Units that can be expressed in terms of other units are called derived units.eg. m/s, joule. ? Systems of units i)CGS ii) FPS iii) MKS iV) SI
