define fundamental and derived physical quantities with one example
Answers
Answer:
Every physical “matter” intrinsically consists of one or more “properties” (such as mass, weight, length, velocity, temperature, current, etc.). By definition, every property of a matter is measurable and quantifiable. Measurement of a property can be carried out with suitable instrument. However, to quantify the measured result, a “magnitude” along with its “unit” is required to present. By definition, a unit of measurement indicates “a standardized and well-defined magnitude of a property of the physical matter
Answer:
A physical quantity is a quantity that can be measured.
physical quantities are classified into fundamental and derived quantities
there are 7 fundamental quantities
length
mass
time
temperature
electric current
luminous intensity
amount of substance
the quantities which depend on the fundamental quantities are called derived quantities.
Eg. Area = l x l
S = d/t
