Universal Gravitation is a fundamental principle in physics that explains how objects with mass attract each other. This force is proportional to the masses of the objects and inversely proportional to the square of the distance between them. For example, the Earth pulls us towards it, while we also exert a tiny gravitational force on the Moon. This concept was first formulated by Isaac Newton in the 17th century. His famous law of universal gravitation helps us understand not only why we stay grounded but also how planets orbit stars and how galaxies interact. It’s a key idea that shapes our understanding of the universe.
