Solution:

When earth moves round the sun then according to Keplers second law, the radius vector drawn from the sun to earth, sweeps out equal areas in equal time, i. e., its areal velocity (or the area swept out by it per unit time) is constant. While in such motion, angular velocity, kinetic energy and potential energy change.
