over in earth sciences, someone asked a question about whether acceleration of objects differs on the earth surface according to location (pole versus equator being the two end member conditions)
I cannot remember the equations that apply and have bailed on looking it up. My thinking is that the velocites are clearly different, and as a result the forces required to cause an acceleration vary according to location, but I fall into the thinking that the acceleration is actually the same for all bodies.
That is, the change in velocity per unit time does not vary with location. Is this correct, and if so, why?
