The Chandra X-ray satellite orbits Earth in a highly elliptical orbit, as shown in the following figure. The force that Earth exerts on the satellite is always directed toward Earth. Is the satellite’s kinetic energy increasing, decreasing, or staying the same at each of the points indicated? Explain your reasoning. (Note: The velocity vectors on the figure are not drawn to scale.)
