Sep 25, 2025 · The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. …

Gravity Concepts and Applications

May 23, 2025 · Gravity wasn’t just something that happened on Earth—it extended into the heavens. For the first time, the same law explained both the fall of an apple and the orbit of the Moon. But even …

Gravity is the force of fundamental attraction between all things that have mass or energy. It feels powerful to us in our daily lives, but it is by far the weakest of the four known forces in nature.

Newton’s universal law of gravitation, formulated in his great work of mathematical physics, the Principia, published in 1687, was the first great work of force unification in physics.

Mar 21, 2025 · Discover the fundamentals of gravitational force, Newton’s Law of Gravity, and how it shapes our universe – all broken down with simple explanations, diagrams, and real-world applications.

We understand that gravity is fundamentally a purely attractive force – it can only pull, never push – and that it is generated by any object with mass. But humankind has been trying to find a better answer …
