A satellite is moving in an orbit around the earth due to

Statement I: Consider a satellite moving in an elliptical orbit around the earth. As the satellite moves, the work done by the gravitational force of the earth on the satellite for any small part of the orbit is zero. Statement II: K_(E) of the satellite in the above described case is not constant as it moves around the earth.
