Question

What are fundamental quantities

Answer 1

A base unit (also referred to as a fundamental unit) is a unit adopted for measurement of abase quantity. A base quantity is one of a conventionally chosen subset of physical quantities, where no subset quantity can be expressed in terms of the others. In theInternational System of Units, there are seven base units: kilogram, metre, candela, second,ampere, kelvin, and mole.

In the language of measurement, quantitiesare quantifiable aspects of the world, such astime, distance, velocity, mass, temperature,energy, and weight, and units are used to describe their magnitude or quantity. Many of these quantities are related to each other by various physical laws, and as a result the units of a quantities can be generally be expressed as a product of powers of other units; for example, momentum is mass multiplied by velocity, while velocity is measured in distance divided by time. These relationships are discussed in dimensional analysis. Those that can be expressed in this fashion in term

Answer 2

the quantities which do not depend on other quantities are called fundamental quantities. they are time, mass and length
