“Accelerated motion is not relative”, ”Equivalence of every frame including accelerated frame” The two above seem to be inconsistent. These are subheading of books (in Japanese ; published in 1998 and 1999).
On a point mass, inertial force acts only in one direction always. Gravity isn’t so. Equivalence principle will be wrong. Under every situation, the law of universal gravitation will act.
