    Undergrad Calculating Force of Gravity with Fg = (G m1 Me)/Re^2

    does the following equation Fg = (G m1 Me)/Re^2 the R is the radius had to get the e subscript neglect the fact that the Earth isn't really a sphere? that the Earth doesn't move in a complete circular orbit? That the Earth experiances a drag force among others as it moves...
