The moon is speeding up.

If it were slowing down, it would fall closer to Earth.

The Earth is the one that is slowing down, due to tidal effects of the moon. That energy is being transferred to the moon.

I think so, anyways!

Thanks. The tidal transfer of momentum occurs in both directions; but the Moon is about one per cent the mass of the Earth, so it shows the same face to us as it orbits (and slowly turns on its axis). A satellite in prograde orbit (moving in orbit the same direction as the parent body turns on its axis) will enjoy a transfer of momentum and its altitude will increase. Even its own transfer of momentum to the parent body will do that. If there’s enough momentum to start with, the satellite will eventually fly off.
