Which law states that every object in the universe attracts every other object?

The Law of Universal Gravitation is a fundamental principle that states every mass attracts every other mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This concept was formulated by Sir Isaac Newton and is crucial in understanding the behavior of celestial bodies, as well as everyday objects.

This law explains why planets orbit stars, moons orbit planets, and even why objects fall to the ground on Earth. It provides a coherent framework for explaining gravitational forces in a variety of contexts, ranging from the motion of galaxies to the fall of an apple from a tree. By emphasizing the universal aspect of gravitational attraction, this law underscores the interconnectedness of all matter in the universe, making it a cornerstone of classical physics.

The other options relate to different principles: the Law of Conservation of Energy pertains to energy stability and transformation, the Laws of Thermodynamics involve heat and energy exchanges in systems, and the Laws of Motion describe the relationship between a body and the forces acting on it. None of these address the gravitational attraction between objects as the Law of Universal Gravitation does.
