Question

4 differences between fundamental quantities and derived quantities

Answer 1

Explanation:

Fundamental units

1. Fundamental units are all those units which are independent of any other unit (including themselves).
2. Fundamental units cannot be broken down into elementary level; in fact, these are elementary unites.
3. Fundamental units cannot be expressed in terms of derived units.
4. Only seven fundamental units exist in SI system
5. Examples of fundamental units along with physical properties are:
6. Examples of fundamental units along with physical properties are:Length (Meter, m)
7. Examples of fundamental units along with physical properties are:Length (Meter, m)Mass (Kilogram, kg)
8. Examples of fundamental units along with physical properties are:Length (Meter, m)Mass (Kilogram, kg)Time (Second, s)
9. Examples of fundamental units along with physical properties are:Length (Meter, m)Mass (Kilogram, kg)Time (Second, s)Temperature (Kelvin, K)
10. 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)

Derived units

1. 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.
2. Derived units can be broken down to its elementary level (composed of fundamental units).
3. Derived units can be expressed in terms of fundamental units.
4. A large number of derived units are available.
5. Examples of derived units:
6. Examples of derived units:Velocity (m/s)
7. Examples of derived units:Velocity (m/s)Acceleration (m2/s)
8. Examples of derived units:Velocity (m/s)Acceleration (m2/s)Momentum (kg-m/s)
9. Examples of derived units:Velocity (m/s)Acceleration (m2/s)Momentum (kg-m/s)Force (N)
10. Examples of derived units:Velocity (m/s)Acceleration (m2/s)Momentum (kg-m/s)Force (N)Density (kg/m3)
11. Examples of derived units:Velocity (m/s)Acceleration (m2/s)Momentum (kg-m/s)Force (N)Density (kg/m3)Heat (J)
12. Examples of derived units:Velocity (m/s)Acceleration (m2/s)Momentum (kg-m/s)Force (N)Density (kg/m3)Heat (J)Energy (J)
13. 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.

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...
