Question

difine fandamental unit and dirave unit​

Answer 1

Answer:

Derived quantity : quantities which are depend on fundamental quantities. ex: Area, volume, density, speed, acceleration, force, velocity etc. Fundamental units : units which are used to measure the fundamental quantities are called fundamental units.(units which are independent on other units)

Answer 2

#Fundamental units are all those units which are independent of any other unit (including themselves). Derived units are all those units which are obtained by multiplying and/or dividing one or more fundamental units with or without introducing any other numerical factor.

#Fundamental units cannot be broken down into elementary level; in fact, these are elementary unites. Derived units can be broken down to its elementary level (composed of fundamental units).

#Fundamental units cannot be expressed in terms of derived units. Derived units can be expressed in terms of fundamental units.

Only seven fundamental units exist in SI system. A large number of derived units are available.

#Examples of fundamental units along with physical properties are:

Length (Meter, m)

Mass (Kilogram, kg)

Time (Second, s)

Temperature (Kelvin, K)

Amount of substance (Mole, mol)

Electric current (Ampere, A)

Luminous intensity (Candela, cd)

#Examples of derived units:

Velocity (m/s)

Acceleration (m2/s)

Momentum (kg-m/s)

Force (N)

Density (kg/m3)

Heat (J)

Energy (J)

Power (W), etc.
