Setting aside the fact that the sun does not rise in relation to the earth, we know that the earth did not "always" experience a sunrise. What about before the earth, the solar system, the galaxy? What about the future? We know that the sun will eventually burn out--no sunrise then. So no, truth is not subjective nor relative.
"On" is conditional upon gravity. Is there an "on" in zero gravity/zero force application? "On" is conditional upon the substance of the table and book. What you previously considered true was conditional, subjective and relative.
Gravitational force has a direct relationship with mass. That relationship is objective. Just because a proposition contains a relationtional statement that does not meant the truth value of that proposition is subjective.
