13.2: Newton's Law of Universal Gravitation
Newton's Law of Universal Gravitation. Newton noted that objects at Earth's surface (hence at a distance of R E from the center of Earth) have an acceleration of g, but the Moon, at a distance of about 60 R E, has a centripetal acceleration about (60) 2 times smaller than g. He could explain this by postulating that a force exists between …

Centripetal force is a fundamental concept in physics, referring to the force that acts on an object moving in a circular path and is directed towards the center around which the object is moving.
