There are several.
They are the Metre, Gramme, Second, and I think the Volt, Ampere and Coulomb but I stand to be corrected. Where does the Joule come into things?
Because the measurement of current is more convenient.we may take direct reading of current.
The fundamental units are those of the SI system - The unit of Temperature, Kelvin; of Time, the second; of Mass, Kilogram; of brightness, the Candela; of physical quantity, the Mole; and of electrical current, the Ampere. With these units, all fundamental quantities may be described.Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
scalar quantity has only magnitude whereas vector quantity has magnitude as well as direction
Unit
certainty means how are you accurate in measuring a physical quantity. There is always some uncertainty in measuring of any physical quantity . It is given by higenberg's uncertainty principle. Quantum mechanics deals with the physical quantities which have some discreet values. So The measurement is not certain.
Fundamental quantities are quantities that can be measured such as mass, length and temperature. Derived quantities are quantities that has to be calculated such as pressure, volume and work done.AnswerThe SI does not define 'fundamental quantity', instead it uses the term 'Base Unit'. All other units are 'Derived Units', so-called because they are each derived from combinations of Base Units.
Fundamental quantities r those which r independent of other quantities and r scaler and on the other hand derived quantities r those which depends on fundamental quantities!! For example metre sqaure!
the differentiate between fundamental quantity and derived quantity?
It is a derived quantity.
Base quantities (Scalar Quantities) :Independent quantities who have single standard units.- time /seconds-distance/metersDerived Quantities (Vector Quantities):Quantities derived by multiplying or dividing 2 base quantities.- Velocity = distance/timeunit of Velocity = m/s
No, weight is not a fundamental quantity.
There are seven SI fundamental quantities of measurement.Base Quantity/Unit/Abbreviationmass/kilogram/kglength/meter/ mtime/second/selectric current/ampere/Aamount of substance/mole/molthermodynamic temperature/kelvin/Kluminous intensity/candela/cd
In Science, there are seven fundamental quantities. The seven fundamental quantities includes length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.
Derived quantities are quantities which are made or found from other major quantities. There are two types of quantities. Ones are which are recognized throughout the world and using them other quantities are made.
It is a quantity that is not affected by other quantities. It may or may not affect them.
Basic quantities are quantities which can be arrived at without performing any mathematical procedure. Derived quantities are those which can be arrived at only after performing mathematical procedure.
