A circularly moving object requires a centripetal force. What supplies this force for satellites that orbit Earth? The force of friction on a sliding object is 10 N . A 300-kg bear grasping a vertical tree slides down at constant velocity . A horse gallops a distance of 10 kilometers in a time of 30 minutes. A car maintains a constant velocity of 100 km/hr for 10 seconds. A truck is moving at constant velocity. More fuel is required for a rocket that leaves Earth to go to the moon than the other way around . This is because a rocket must move against the greater gravitational field of the earth most of the way. ( If launched from the moon to earth then it would be traveling with the earth's field most of the way ) Gravitational force is indeed acting on a person who falls off a cliff and on a person in a space shuttle . Both are falling under the influence of gravity. Your friend says that the primary reason astronauts in orbit feel weightless is that they are ...
