Gravitational attraction is the force that pulls two objects toward each other. This force depends on the masses of the objects and the distance between them. For example, the larger the mass of an object, like the Earth, the stronger its gravitational pull. This is why we stay grounded on the Earth's surface. Every object in the universe, from tiny apples to massive planets, experiences gravitational attraction. The Moon orbits the Earth due to this force, while the Sun keeps the Earth and other planets in orbit around it. Gravitational attraction is essential for the structure and movement of celestial bodies.
