Key Concepts

Gravitation

Gravitation is a fundamental interaction in nature that causes all objects with mass or energy to be attracted to one another. It is a pervasive force that influences the structure and behavior of the universe, from the falling of an apple to the orbits of planets and galaxies.

Newton's Law of Universal Gravitation

Newton's law defines gravitation as the force that acts between two bodies, stating that the force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This classical description provides a clear mathematical framework for understanding everyday gravitational interactions.

General Relativity

General relativity offers a modern perspective on gravitation by describing it as the curvature of spacetime caused by the presence of mass and energy. This concept replaces the idea of a classical force with a geometric property of the universe, explaining phenomena such as the bending of light around massive objects and the dynamics of objects in strong gravitational fields.
