Is Gravity Energy? Yes, it may seem minor, but (as suggested in the comments) there is a substancial difference between using a noun or a verb, the latter making more sense for an interaction.

Is Gravity Energy? If I get your point right, @JoeH, you're saying that gravitation (a verb) is more suited to the correct interpretation as an interaction, whereas gravity (a noun) tends to be picked up as a thing?
