Question

4 differences between fundamental quantities and derived quantities

Answer 1

Explanation:

Fundamental unit : fundamental units are independent of any other unit.

2) can't be broken down into elementary level as themselves are elementary units.

3)can't be expressed in form of derived units.

4)Only 7 fundamental units are included in SI unit.

5) e. g. Time (second)

Length ( meter )

Mass ( kilogram)

Temperature ( Kelvin)

Amt. Of substance ( mole )

Electric current (Ampere )

Luminous intensity ( candela)

Derived units : derived units are those units which were obtained through fundamental units.

2)Can be broken down to elementary level

3)can be expressed in term of fundamental units.

4) large number of derived units are there

5) e. g. Velocity (m/s)

Acceleration (m/s ^2)

Force (kg m/s^2)

Etc.

Answer 2

Answer:

Fundamental Quantities➾

❃ These are the physical quantities that cannot be expressed in terms of other quantities.

❃ These quantities do not depend on other quantities.

❃ EX:- Length, mass and time.

Derived Quantities➾

❃ These are the quantities obtained by combining fundamental quantities either by multiplication or division or both.

❃ These quantities depend upon fundamental quantities.

❃ EX:- Area, acceleration,volume, velocity etc...
