Question

Simple difference between fundamental quality and derived quality and the units deference between fundamental quality and derived quality.

Answer 1

Hii...

=> Fundamental quantities are the base units in a given measurement system. They can also be directly measured. Derived Quantities: While fundamental quantities can be directly measured, derived ones must be calculated.

Answer 2

Explanation:

Fundamental quality:

1. The quantities that do not depend on any other physical quantity for their measurements are known as fundamental quantities.
2. These quantities cannot be expressed in terms of derived units.
3. There are only seven fundamental units, which exist in Metric System or SI system.
4. Examples:  Time (Second, s) ,Length (Meter, m) ,Mass (Kilogram, kg) ,Temperature (Kelvin, K) ,Electric current (Ampere, A) ,Amount of substance (Mole, mole),Luminous intensity (Candela, cd).

Derived quality:

1. The products and/or ratios of the fundamental quantities that exist in a system of units are known as a derived quantity.
2. These quantities can be expressed in terms of fundamental units.
3. There are a large number of derived units, which exist in the Metric System.
4. Examples:  Heat (J) ,Force (N) ,Power (W) ,Energy (J) ,Velocity (m/s) ,Density (kg/m3) ,Momentum (kg-m/s) ,Acceleration (m2/s).
