Quantities And Units

QUANTITIES AND UNITS

Basic Competence Describe fundemental quantities and derived quantities and also their units.

Indicators Student can be able to : 2. Identification physical quantities in daily life and collected in the fundamental quantities and derive quantites. 3. Using International units in the measuring. 4. Comunicating the simple units of length, mass and time.

Derived Quantities

Fundamental Quantities

Fundamental Quantities Can you mention some examples of product picture descriptions, which one of fundamental quantities? Roll meter, Detergent and floor cleaner because : the units of product are meter, kg and ml

Fundamental Quantities Example of fundamental quantities : 2. Length 3. Mass 4. Time 5. Temperature

The Units of Fundamental Quantities In The International System Unit Length is meter Mass is Kg Time is second Temperature is Kelvin

Derived Quantities

Can you mention example of derived quantities ? 1. 2. 3. 4. 5. 6. 7.

Volume = volume Area = luas Velocity = kecepatan Force = gaya Density = massa jenis Acceleration = percepatan etc

Can you mention the units of derived quantities ? (in the International System Unit) • • • • • • •

Volume = metre cubic (m3) Area = meter square (m2) Velocity = m/s Force = Newton (N) Density = kg/m3) Acceleration = m/s2 etc

Conclusion • The Fundamental Quantities are conventionally established by the International Conference on weight and measurement. Fundamental Quantities
