The force responsible for keeping us anchored to the ground is "gravity." Gravity is a natural phenomenon that attracts objects with mass towards each other, and on Earth, it pulls everything toward its center. This force not only keeps us grounded but also governs the movement of celestial bodies in space. The strength of gravity depends on an object's mass and the distance between objects, explaining why larger bodies like planets exert a stronger gravitational pull. Without gravity, life as we know it would not exist, as it is fundamental to many physical processes.
