Ever wondered why apples fall down instead of up? Or what keeps the moon circling Earth? The answer lies in a fundamental principle: Newton's Law of Universal Gravitation. This elegant law, formulated by Sir Isaac Newton, states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
In simpler terms, the bigger the objects and the closer they are, the stronger the gravitational pull. This force is what keeps planets in orbit around the Sun, governs the tides on Earth, and even influences the formation of galaxies. While we can't see it, gravity is a constant presence, shaping the universe as we know it. It's a testament to Newton's genius that this single law explains so many phenomena, from falling fruit to celestial mechanics. So next time you see an apple fall, remember the invisible force that's at play – Newton's Law of Universal Gravitation!
