What are the two properties of physical quantities?

• speed and direction

• magnitude and unit

• distance and mass

• temperature and numbers

How do we classify physical quantities? (choose two)

• fundamental

• derived

• magnitudes

• units

Their measurement in most cases can be done directly by using specific instruments.

• fundamental or base quantities

• amounts or magnitudes of measure

• derived quantities

• units of measure

Characterized because they emerge from relationships established between the fundamental quantities.

• base quantities

• unit values

• derived quantities

• magnitude values

Universal system of measure patterns established in 1960 with headquarters in France.
