Based on the above table, determine the derived quantities and its international units.
Solution
Density
The equation of density is ρ = m / V
m = mass (its international unit is kilogram, abbreviated kg)
V = volume (its international unit is a cubic meter, abbreviated m3)
ρ = density (its international unit is kilogram per cubic meter, abbreviated kg/m3)
Force
The equation of force is F = m a
m = mass (its international unit is kilogram, abbreviated kg)
a = acceleration (its international unit is meters per second squared, abbreviated m/s2)
F = force (its international unit is kilogram meters per second squared, abbreviated kg m/s2)
Velocity
The equation of velocity is v = s / t
s = distance (its international unit is meter, abbreviated m)
t = time (its international unit is second, abbreviated s)
v = velocity (its international unit is meter per second, abbreviated m/s)
Area
The equation of area is A = l x l
l = length (its international unit is meter, abbreviated m)
A = area (its international unit is meter squared, abbreviated m2)
Temperature
Temperature is base quantity. Symbol of temperature is T and its international unit is Kelvin, abbreviated K.
The derived quantities and its international units are shown by number (1), (2), and (3).
