Principle of Homogeneity of Dimensions

-

Principle of Homogeneity of Dimensions :


This principle states that, "In a dimensionally correct physical relation the dimensions of each and every term on both sides of the relation must be same".

According to this principle ;

(1) We can add or subtract only those physical quantities which have same nature (means if they have same dimensions).

(2) A physical relation, must be dimensionally homogeneous i.e., all the terms on both sides of the relation must have the same dimensions.
