... – If we insist that Newton’s 2nd Law holds in a noninertial reference frame. To make the force equations look as if the reference frame is an inertial one, it’s necessary to introduce Fictitious Forces. – Technically, it’s the coordinate transformation from the inertial frame to the non-inertial one ...
