Here's a breakdown:
* Universal Law of Gravitation: This law, formulated by Sir Isaac Newton, states that every particle in the universe attracts every other particle with a force that is:
* Proportional to the product of their masses: The more massive the objects, the stronger the gravitational attraction.
* Inversely proportional to the square of the distance between their centers: The farther apart the objects, the weaker the gravitational attraction.
* Gravitational Attraction: While gravity is a weak force on the scale of everyday objects, it's the dominant force on astronomical scales. It's what holds planets in orbit around stars, stars in galaxies, and galaxies together in clusters.
Note: While gravity is always attractive, it's important to understand that there are other forces at play in the universe, some of which can be repulsive. For example, the electromagnetic force can be both attractive and repulsive, depending on the charges involved.
