Question

6. Find the fundamental units involved in the following derived units.
(i) Newton(N) (ii) Watt (W) (iii) Joule (1)
(iv) Pascal (Pa)
(v) Cubic metre​

Answer 1

Answer:

Fundamental unit:

Fundamental units are those set of unrelated units of measurement which are defined arbitrarily and from which other units are formed or derived. It is the unit of measurement for a measurable physical property.

The fundamental units of

(i.) Newton (N): kg(m/s²) = kg.m.s⁻²

(ii.) Watt (W): kg(m²/s³) = kg.m².s⁻³

(iii.) Joule (J): N.m = kg.m².s⁻²

(iv.) Pascal (Pa): kg.m⁻¹.s⁻²

(v.) Cubic metre: m³
