¹ An inertial frame is the one, which is either stationary or moving with the constant velocity. When the frame itself moves with velocity as function of time, it has its own acceleration and is called non-inertial frame.

² Different notations are in use to represent a vector. In this book we are using notations, the bold and an arrow over the vector like .

³ It is common practice to represent a vector by a column matrix. This is not used here because it is convenient to write it in a row form to save a few lines. Even those following the former practice use transpose of the matrix while writing it to save space. Recall transpose of ...
