The law that determines the strength of a pull is known as Newton's Law of Universal Gravitation.
This law states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
This law applies to everyday situations such as the force of gravity between objects on Earth, the motion of planets around the sun, and the attraction between the moon and Earth.
This law is related to other laws of motion, specifically Newton's laws of motion. It is a fundamental law of physics that explains the force of gravity and its effects on objects.
While Newton's Law of Universal Gravitation is a fundamental law of physics, it does not account for extreme situations such as those involving black holes or objects traveling at the speed of light. In these scenarios, Einstein's theory of general relativity is needed to accurately describe the behavior of gravity.
