Here's the breakdown:
* Newton's Law of Universal Gravitation: This law states that every particle of matter in the Universe attracts every other particle with a force that is:
* Proportional to the product of their masses: Larger masses exert a stronger gravitational pull.
* Inversely proportional to the square of the distance between their centers: The force weakens rapidly with increasing distance.
This means that any two objects with mass will experience a force pulling them towards each other. This force is what causes apples to fall to the ground, planets to orbit the Sun, and galaxies to clump together.
While this theory is very successful in explaining many aspects of gravity, it's important to note that it doesn't explain everything. For example, it doesn't account for the effects of gravity on very strong gravitational fields like those found near black holes. For those situations, we need to turn to Einstein's Theory of General Relativity.
