Question

correctness of the equation ischecked the method of dimensional analysis.a,name the principle used. b, check the correctness of the equation v=v0+at

Answer 1

The principle used is principle of homogeneity.

The dimensions of v are LT^-1

Similarly, dimensions of v0 and a/t are LT^-1 and LT^-2(T)= LT^-1.

Hence, adding similar nature quantities give us LT^-1= LT^-1.
