California New York Colorado Wyoming 4. If a satellite's radial velocity is zero at all times, its orbit must be Geosynchronous. Elliptical. Circular. Parabolic. 5. The circular path of a satellite orbiting the Earth is characterized by a constant Radial distance. All of these Acceleration. Speed. 6. A "weightless" astronaut in an orbiting shuttle is Shielded from the Earth's gravitational field. Beyond the pull of gravity. Pulled only by gravitation to the shuttle which cancels the Earth's gravitational pull. Like the shuttle, pulled by Earth's gravitation. 7.
