The term for the force that keeps objects grounded is "gravity." This fundamental force is responsible for attracting two bodies towards each other, with the strength of this attraction proportional to their masses and inversely related to the square of the distance between them. Gravity plays a crucial role in keeping objects anchored to the Earth, influencing everything from the falling of an apple to the ground to the orbits of planets around the sun. In addition to its role on Earth, gravity governs the motion of celestial bodies throughout the universe and is pivotal in fields such as astrophysics and engineering.
