Zorluk: KolayFundamental and Derived Quantities

Match each physical quantity to its correct classification as either a fundamental or a derived physical quantity.

  • Luminous intensityFundamental quantity measuring light brightness in candela
  • MassFundamental quantity measuring the quantity of matter in a body
  • ForceDerived quantity defined as the rate of change of linear momentum
  • Electric potentialDerived quantity defined as work done per unit electric charge

Cevap

Luminous intensity matches with fundamental quantity measuring light brightness; Mass matches with fundamental quantity measuring quantity of matter; Force matches with derived quantity defined as rate of change of linear momentum; Electric potential matches with derived quantity defined as work done per unit electric charge.
Luminous intensity and mass are two of the seven base SI quantities. Force and electric potential are derived quantities defined through mathematical combinations of base quantities.

Adım Adım Çözüm

1
Identify the fundamental physical quantities
Luminous intensity and Mass are fundamental physical quantities.
Fundamental physical quantities are basic quantities that do not depend on any other physical quantity for their definition.
2
Identify the derived physical quantities
Force and Electric potential are derived physical quantities.
Derived physical quantities are obtained by combining fundamental physical quantities through mathematical relationships.

Anahtar Kavram

Fundamental quantities (length, mass, time, electric current, thermodynamic temperature, amount of substance, luminous intensity) are independent, whereas derived quantities are formed by combining fundamental quantities.
