The moon is still rotating quite happily relative to the Sun and the remote galaxies it just so happens that its orbital period around the Earth and its rate of rotation are the same
With regards to the moon being upside down viewed from New ZeaLand people often remark on Whirpools etc rotating in the opposite way down under, but of course they don't they still rotate in the same way relative to the Earths rotation but they just look different because you are upside down
If I board the elevator that travels from the antipodeon islands via the centre of the Earth to the UK, I start with my feet pointing towards the centre of the earth but after 42 minutes when I arrive in the UK my head points towards the centre of the earth, I call this being converted from rightway up to upsidedown.
You're not upside down when you're in New Zealand.
This is because the gravitational field inside a uniform thick spherical shell is zero at all points inside the shell.
Do you want to work out the transit time for any variation of g or for a linear change. If the first have you done any calculus?
I have visited Australia several times and have noticed that the water spirals down the waste pipe the the same way relative to the earths rotation as it doe's in Britain.The water does not rotate in a different direction it is just that you are viewing it from a different perspective
