State the principle of homogeneity of dimensions.
(N/A) The principle of homogeneity of dimensions states that a physical equation is dimensionally correct only if the dimensions of all the terms on both sides of the equation are the same.
In other words,we can only add,subtract,or equate physical quantities that have the same dimensions.
For example,in the equation $v = u + at$,the dimensions of $v$,$u$,and $at$ must all be equal to $[LT^{-1}]$.
