Defining Gravity
Gravity is a fundamental natural force of attraction that exists between any two objects with mass or energy. The strength of this attraction depends on the masses of the objects and the distance between them; more massive objects exert a stronger gravitational pull, and the pull weakens with increasing distance.
How Gravity Works in Our World
On Earth, gravity is what keeps us grounded, causes objects to fall, and makes rain come down. In space, it's the force responsible for planets orbiting the Sun, moons orbiting planets, and the formation of galaxies. It's a universal force, meaning it operates throughout the entire cosmos, dictating the structure and movement of celestial bodies.
