An elevator is supported by a cable and moving downward through the elevator shaft at a constant speed. How does the upward tension force compare to the downward force of gravity? O The upward tension force is stronger than the downward force of gravity. The downward force of gravity is stronger than the upward tension force. The tension force and the force of gravity are of equal strength.
