The units of gravitational potential are J/kg not J. The beauty of dealing with potential is that it is a scalar, not a vector like force. So you add potentials algebraically; you do not need to use the parallelogram rule. Potential does not change sign if the bodies of interest are in the opposite direction. It does not depend at all on the angle ...

I'm not familiar with the math, but am wondering if the 4 should be a 2 instead, (for hemisphere). The Moon's day is about 13.5 of our days, so at its highest the lit side and dark side of the Moon can vary up to 500 degrees F, from about 250F on the lit side to about -250F on the dark side. I would suggest that our atmosphere - which is literally mass ...

I am certain that mathematical analysis of tidal locking has been done many times but I have failed to find such an analysis where the mechanism for the transfer of angular momentum to spin angular momentum is included which is the question which has been asked. Perhaps someone is able to produce a reference or an analysis? Having experienced on a number ...

Their claim that atmospheric pressure would increase if moon is over head is wrong. Atmospheric pressure at same height is same. This follows directly from Pascals law. So, even if moon is directly upwards or whatever is the shape of bulge out. It does not matter. If there was an increase in atmospheric Pressure , it will create a pressure gradient. This ...
