Quizplus · Accepted Answer

In a circular orbit, the satellite moves with a constant speed, as it covers the same distance in the same time interval. The acceleration of the satellite is also constant, and it is directed towards the center of the circular orbit, which maintains the circular motion. The radial distance, which is the distance between the satellite and the center of the Earth, is also constant in a circular orbit. Therefore, all of these options (speed, acceleration, and radial distance) are characterized by a constant in a circular orbit.
