I'm sorry, but your definition is contrary to modern usage, including strict scientific usage.
"Gravitation" is, in my experience, used in a qualitative sense and never used to refer to objects with mere gravitational influence on one another (stellar objects in orbit, etc). It specifically refers to the fact of one object decidedly moving towards another, independent of the cause of the force.
Show specifically where my definition is contrary to scientific usage.
Note:

Falling is the action of attractive acceleration of the smaller mass to the larger mass minus any force propelling it.

Read this statement, then read yours. Note, the "attractive acceleration" is in this case caused by "Gravity" or "Gravitation". The motion of the two celestial bodies, for example, would in fact be referred to as "Gravitation". If I wanted to point out the process that the two celestial bodies are engaging in, I could say with scientific confidence, "Look at the heliocentric elliptical orbit of the earth to the sun, and how on the return epoch they gravitate towards each other.". This would be a scientifically accurate statement.
I never referred to "Gravitation" as "objects with mere gravitational influence on each other". The objects are separate.
"Gravity" is one of those terms that like "Theory" is misunderstood in common parlance.
Statements like, "Oh he doesn't realize the gravity of the situation." really just show the disconnect between the literal, scientific application of the word, and the actual, scientific understanding.

Here, and excerpt from one:
"Surprisingly, the first of Kepler’s laws—that the planetary paths are elliptical—is the toughest to prove beginning with Newton’s assumption of inverse-square gravitation"

Pay attention to the bolded parts.
Yup.
I have to say I expected more from you. You are usually thorough, but in this case you are not.
ANYBODY on this forum or elsewhere that has taken Introduction to Science (101 level) or more advanced science courses has been introduced to the "Scientific Process".
Anybody who has taken said classes would know that "Theory" represents an entire model denoting a hypothesis that has met its burden of falsifiability and validation. All current determinations of carefully examined and applied datum have been validated and are far more refined than the common public usage of the word "Theory".
The same applies to the word "Gravity" and all terms that utilize it as a root.
Gravity is: F = G × [(m1m2)/r²]
This equation was obtained through the same series of falsification and validation, and found to be the BEST explanation for the purpose of the initially observed "falling".
Hence, "Theory of Gravity".
The same stands true for theory of evolution, the theory of tectonic plate shift, and thousands of other theories.
You come across at times as an English Major, which is cool. I appreciate a certain command of the language.
However, it seems you do not possess the prerequisite courses to actually know what I am talking about in reference to the scientific model.
As I sit here, I realize there is another word that could be used to demonstrate the difference.
"Cindy is smokin hot."
This statement would be used in common usage to denote attractiveness. The word "Hot" being a colloquialism. It transfers the term of literal heat to the sensation of attractiveness and likens it to fire.
"That's a great theory you have there." could have different depths if stated by a 6 year old to his sister, and then again from a professor to his grad student. Willing to bet which one is applying the scientific model?
I think there's more to this than your grasping, and the POINT, is to show that "Theories" in scientific circles are very well vetted understandings about our natural world. This INCLUDES the Theory of Evolution.
To disprove these theories in a field of occupation that THRIVES on things that throw theories on end, creating excitement for kicking the entire theory back into the hypothesis stage, would earn you a Nobel prize.
Disprove Evolution? Nobel prize, and I promise you scientists would LOVE you to do that. It just means they are still needed, and the new evidence, whatever it may be, is fresh air and puts their minds back to work.
As to the definition, I don't really care for the Dictionary definition. Please, next quarter, take some science classes. Even if its just Science 101. Question the instructor on what comprises a "Theory".
Then just sit back and listen.
