Explanation:

↪️In mechanics, length, mass and time are three fundamental quantities. For the units of these basic quantities, following systems have been used: (1) C.G.S. System: In this system, the unit of length is centimetre, unit of mass is gram and the unit of time is second.

•Example

↪️Some physical quantities are more fundamental than others. In physics, there are seven fundamental physical quantities that are measured in base or physical fundamental units: length, mass, time, electric current temperature, amount of substance, and luminous intensity.
