What are the examples of derived quantities?
Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations….
| Derived quantity | Name | Symbol |
|---|---|---|
| speed, velocity | meter per second | m/s |
| acceleration | meter per second squared | m/s2 |
| wave number | reciprocal meter | m-1 |
| mass density | kilogram per cubic meter | kg/m3 |
What are the five examples of derived quantities?
There are some commonly used derived units which includes:
- Pressure = AreaForce=m2N.
- Mass density= m3kg.
- Specific volume = kgm3.
- Current density = meter2Ampere=m2A.
- Magnetic field strength = MeterAmpere=mA.
- Capacitance =Farad=F=VC=m−2kg−1s4A2.
What are the examples of fundamental unit and derived unit?
The units which are independent of each other are known as Fundamental Units. Derived Units are derived from Fundamental Units. For example, meter is a fundamental unit of length and second is a fundamental unit of time. However, meter per second (ms-1) is a derived unit of velocity.
What are the 10 derived quantities?
SI-Derived Units

What are the examples of fundamental units?
The examples of fundamental units are:
- Mass in kilogram.
- Length in meter.
- Time in seconds.
- Temperature in kelvin.
- Light intensity in candela.
- Electric current in Ampere.
What are the 7 fundamental quantities?
The present SI has seven base quantities: time, length, mass, electric current, thermodynamic temperature, amount of substance, and luminous intensity.
What are fundamental quantities?
Hint: Fundamental quantities are mass, time, current, length, temperature, amount of substance and luminous intensity. All other physical quantities are derived quantities and can be made from fundamental quantities. Momentum is the product of mass and velocity.
What are derived quantities?
Derived quantities are quantities that are calculated from two or more measurements. Derived quantities cannot be measured directly. They can only be computed. Many derived quantities are calculated in physical science.
