The Earth's gravity exerts no torque on a satellite orbiting the Earth in an elliptical orbit. Compare the motion of the satellite at the point nearest the Earth (perigee) to the motion at the point farthest from the Earth (apogee). At these two points:

a. the tangential velocities are the same.
c. the angular momenta are the same.
b. the angular velocities are the same.
d. the kinetic energies are the same.
