When in orbit, a satellite such as the space shuttle is

A. simply a projectile.

B. in non-accelerated motion.

C. free from Earth's gravity.

In orbit, a satellite is completely controlled by the forces of gravity

between it and the body it's orbiting. That's what keeps it in orbit.

Without a force constantly drawing it toward the center, it would

sail off in a straight line.

Since there is always a force acting on it, its motion is constantly

accelerated.

The satellite can be considered a projectile.
