WebYup, the strength of gravity changes from about 9.78 m/s^2 at the equator to about 9.83 m/s^2 at the poles, mostly because of the spin of the earth and the resulting centrifugal force. Gravity also changes depending on how high up you are: the further you get from the center of mass the lower the gravity. WebA perfectly circular obit has an eccentricity of 0, which is not at all flattened. So, all ellipses have an eccentricity between 0 and 1.
