|---|---|---|
| mass density | kilogram per cubic meter | kg/m3 |
| specific volume | cubic meter per kilogram | m3/kg |
| current density | ampere per square meter | A/m2 |

What are derived quantities give example?
Derived quantities are the quantities which are expressed in terms of fundamental quantities and based on seven basic fundamental units. For example, area,volume,force,pressure,density etc are few derived quantities.
What are basic and derived quantities?
Base units are defined by a particular process of measuring a base quantity whereas derived units are defined as algebraic combinations of base units. b. A base quantity is chosen by convention and practical considerations. Derived quantities are expressed as algebraic combinations of base quantities.
What are derived quantities and derived units give examples?

What is fundamental and derived quantities?
Fundamental quantity: quantities which are independent on other physical quantity. ex: length, mass, time, current, amount of substance, luminous intensity, thermodynamic temperature, Derived quantity: quantities which depend on fundamental quantities.
What are derived quantities give examples Class 11?
The quantities that are derived using the fundamental quantities are called derived quantities. The units that are used to measure these derived quantities are called derived units. Examples: Force, Velocity, Density, Heat, Power, Energy, Momentum, Acceleration. 4 (8) (23)
What are base and derived quantities in physics?
Base quantities are physical quantities that cannot be defined in terms of other quantities. Table shows five base quantities and their respective SI units. Derived quantities are physical quantities derived from combinations of base quantities through multiplication.
What do you understand by fundamental and derived quantities give examples?
Which is an example of a derived quantity?
Some examples of derived quantities are: Derived Quantity like speed depends upon length and time. Hence it is called derived quantities.
How are fundamental quantities derived from other quantities?
The Concept of Fundamental Quantities Fundamental quantities are physical quantities whose dimensions and units are not usually derived from other physical quantities. Basically, there are three fundamental quantities in mechanics.
How many fundamental quantities are there in physics?
Fundamental Quantities. The quantities that do not depend on any other physical quantity for their measurement are known as fundamental quantities. These quantities do not take support of other physical quantities for its measurement. There are only 7 fundamental physical quantities. And rest of all other quantities are derived quantities.
What are physical quantities that depend on other quantities?
The Physical quantities that depend upon other physical quantity for its measurement are known as derived quantities. The measurement of derived quantities directly depends upon other quantities.
