Question

What is a derived unit?

Answer 1

def: derived unit (plural derived units) (In the SI system of units) Any unit derived from one of the seven base units of length (meter), mass (kilogram), time (second), electric current (ampere), thermodynamic temperature (kelvin), amount of substance (mole) and luminous intensity (candela).

Example: Speed = Distance/time.

answer: a unit of measurement obtained by multiplication or division of the base units of a system without the introduction of numerical factors.

Answer 2

A derived unit is a unit of measurement that is derived from one or more base units.

Step-by-step explanation:

Base units are fundamental units that are used to measure fundamental physical quantities such as length, mass, time, electric current, temperature, amount of substance, and luminous intensity. Derived units, on the other hand, are combinations of these base units that are used to measure derived quantities, which are derived from the fundamental quantities.

Derived units are formed through mathematical combinations of base units, often through multiplication or division. For example, the unit of speed is derived by dividing the unit of length (such as meters) by the unit of time (such as seconds), resulting in meters per second (m/s). Other examples of derived units include the unit of area (square meters), unit of volume (cubic meters), unit of force (newton), unit of energy (joule), and many more.

These derived units allow for the measurement of various quantities and phenomena beyond the fundamental units, catering to the diverse needs of scientific, engineering, and everyday applications.
