Inertial Force and Gravity are Different Things (rewritten) (クリ)
◎ Inertia Force
1) Between inertial force and motion of a mass point in space, there will be direct connection.
2) Position in space has no meaning. Space is homogeneous isotropic.
3) Absolute space is required.
◎ Gravity
1) Between gravity and motion of a mass point in space, there will be no direct connection.
2) Position in space has meaning. As a gravitational field. Space is not homogeneous isotropic.
3) Absolute space is not required.
