Orbital Motion

Question 1

Which statements accurately describe satellite motion? Check all that apply.Gravity is the only force acting on a satellite.Inertia is the only cause of a satellite’s circular motion.Air resistance prevents satellites from staying in orbit for very long.Circular orbits result from the interaction between gravity and inertia.Gravity provides the centripetal force for satellites.Satellites are in free fall around Earth or other central objects.
