fundamental quantity
TRANSCRIPT
Describe fundemental quantities and derived quantities and also their units.
Student can be able to :1. Identification physical quantities in
daily life and collected in the fundamental quantities and derive quantites.
2. Using International units in the measuring.
3. Comunicating the simple units of length, mass and time.
