In Newton's Law is F=ma?, explored the issue of whether or not this formulation was equivalent to Newton's actual statement of his 2nd Law. Today I want to further explore the topic of [logical?] equivalence. In general, I want to know what it means to say that two statements, $P$ and $Q$, are equivalent.

Newton's Law is F=ma?
This is a brief exploration on the logical structure of Newtonian mechanics.
When physicists teach classical mechanics, they often refer to Newton's 2nd Law as "F=ma" or more technically as:
