The force that attracts two bodies towards each other is known as gravity. This fundamental force of nature pulls objects with mass towards one another, and its strength is proportional to the masses of the objects and inversely proportional to the square of the distance between their centers, as described by Newton's law of universal gravitation. Gravity is responsible for various phenomena, including the orbits of planets, the falling of objects toward the earth, and the tides in oceans, playing a crucial role in the structure and dynamics of the universe.
