No, they would have the same angular velocity if they were at the same orbital radius. Any mechanism that pushes a body into a different orbit does so by adding or removing angular momentum.neufer wrote:Were the inner moons somehow pushed out to the orbit of Dione
they would be expected to have the less angular velocity than Dione.
Both the leading and trailing faces will see impacts at the same velocity from debris in a prograde orbit similar to Dione's. The leading edge sees impacts from retrograde debris, and there is a clear asymmetry when considering either debris in solar orbit, or in highly eccentric orbits around Saturn.
