Areal velocity

Vedclass · Answer

(C) According to Kepler's second law of planetary motion,which also applies to satellites orbiting a central body,the radius vector joining the satellite to the center of the Earth sweeps out equal areas in equal intervals of time.This implies that the areal velocity $(dA/dt)$ of the satellite remains constant throughout its orbit.While the angular velocity,kinetic energy,and potential energy change as the distance of the satellite from the Earth varies in an elliptical orbit,the areal velocity remains constant due to the conservation of angular momentum.

When a satellite moves around the earth in a certain orbit,the quantity which remains constant is .........
