Rikku moved the moon to where the moon actually is in space. Significantly further then nagato did. To simply use a constant gravity here would be a mistake; we can't just assume rock is going to be pulled towards earth at 9.8 m/s the whole trip. I'm also now neglecting the forces in between the rock, as the moon does have a significant amount of heat, pressure and gravitational forces to consider when moving it around.
I'm going to skip the initial calculations this time and simply grab the mass of the actual moon. rikku was messing around with: 7.34767309 × 10^22 kilograms, or 73476700000000000000000 kilograms.
The moon accelerates towards the earth at around 0.16 m/s. Assuming a polynomial relationship (it isn't really but close enough) over the 384400Km to the moon, we get the energy Rikku used was equal to :
m * g(h) * h = m * (1/3) * g * h = 9.14357753 × 10^31 Joules. This is more energy than the human race has ever produced. The sun produces 1.4 x 10^31 Joules in one hour.
