combinación de las magnitudes fundamentales.
• Magnitudes Escalares:
• Son aquellas magnitudes que para estar bien definidas
basta conocer únicamente su valor numérico.
Toda cantidad numérica,
función trigonométrica,
función logarítmica,
tendrá por formula
dimensional 1
Las magnitudes no
cumplen con las leyes de
la suma o resta aritmética.
[2010]=1[senx]
=1[log20]=1[ln
25]=1
[π]=1
