Physics / Estimation and Units

Physics / Estimation and Units

Physics, like other branches of science requires experimental study which involves measurements. Measurement is the process of comparison of the given physical quantity with the known standard quantity of the same nature. Learn about two different types of units- fundamental units and derived units.
In mechanics, length, mass and time are the three fundamental quantities. Understand the S.I. unit system for the measurement of length, mass, and time.
