Hello forum.

Earlier in class today i was looking a the /sci/ board.
I often spend a lot of time there and i get really fascinated with the different topics and opinions.
Once particular topic caught my eye today though.

"Does the moon effect falling/thrown items on earth? Since the moons energy controls the tides."

I am no Mathematician or a scientific genius, but i believe the moon does effect other objects, somewhat at least.
If the moons energy is able to control a mass amount of liquid, why shouldn't it also have an impact on a flying rock (Or another object).

That's just my two cents.
What do you guys think?

So there's this one guy named Newton... (http://en.wikipedia.org/wiki/Newton's_law_of_universal_gravitation)

The wikipedia article doesn't mention anything about the tides and such.

Does it really need to? It still answers your question. Any object that has mass attracts any other object with mass. (Newton's law of universal gravitation) More mass, more gravitational force. More distance, less gravitational force.

So yes, the moon would affect something like a falling ball on this planet. Hell, even pluto's moon would have an effect on that ball.

Of course there is an effect, but I would estimate that it's largely negligible.

I suppose it would. The moon has a gravitational pull, no matter how small. It effects the tides and it effects people's moods so yeah, it effects everything else.
