The tide-generating force is inversely proportional to the cube of the distance. - True There is no horizontal tide-generating force on Earth at points directly below and opposite the Moon. - True The barycenter follows: - a smooth orbit around the Sun. The difference between centripetal forces and gravitational forces is called the: - resultant force. t A If the resultant force has a significant horizontal component (tangential to Earth's surface), it produces tidal bulges on Earth, cre...
