Question

Quizplus · Accepted Answer

In a circular orbit, the satellite moves at a constant speed because the gravitational force of the Earth provides the centripetal force necessary to keep the satellite moving in a circular path. The acceleration of the satellite is also constant because it is constantly changing direction, even though its speed remains unchanged. The radial distance between the satellite and the center of the Earth also remains constant. Therefore, all of the above options are correct.
