Gravity exerts a force on objects, causing them to be attracted toward one another, particularly toward larger masses like Earth. This force gives weight to objects, allowing them to fall toward the ground when dropped. The strength of gravity decreases with distance; therefore, objects farther from mass experience reduced gravitational pull. Gravity plays a fundamental role in maintaining celestial structures, like orbits of planets around the sun and moons around planets. Everyday phenomena, like the motion of a ball or the flow of water, are all influenced by gravity.
